STORY OF TWO VACCINES

In India, there are two COVID-19 Vaccines available for mass vaccination, namely COVISHIELD and India’s first indigenous Vaccine COVAXINE. India first vaccinated frontline workers engaged in fighting with Corona Virus like Doctors, Nurses and all other health workers including police, Ambulance Drivers, Sweepers etc.

The second phase of the COVID-19 vaccination drive has already begun in India from Mar 01, 21 with these two Vaccines. Here is a comparative study of both the vaccines – Covaxin and Covishield.

DEVELOPERS : Covaxin has been developed by Hyderabad-based Bharat Biotech International Ltd in association with the Indian Council of Medical Research (ICMR) and the National Institute of Virology (NIV). Covaxin is an inactivated vaccine, which has been prepared on a tried and tested platform of dead viruses.

This vaccine is developed with Whole-Virion Inactivated Vero Cell-derived technology. They contain inactivated viruses, which can not infect a person but still can teach the immune system to prepare a defence mechanism against the active virus.

These conventional vaccines have been in use for decades now. There are vaccines for some other diseases as well which are made using the same technology.

Covishield has been developed by the Oxford-AstraZeneca and is being manufactured by the Serum Institute of India (SII). Covishield has been prepared using the viral vector platform which is a totally different technology.

A chimpanzee adenovirus – ChAdOx1 – has been modified to enable it to carry the COVID-19 spike protein into the cells of humans. Well, this cold virus is basically incapable of infecting the receiver but can very well teach the immune system to prepare a mechanism against such viruses. The exact technology was used to prepare vaccines for viruses like Ebola.

DOSES : There is no difference between the two vaccines in terms of dosage. Both of them follow a two-dose regimen, administered 28 days apart.

STORAGE : Both Covishield and Covaxin can be stored at 2-8 degrees Centigrade, which is a household refrigerator temperature. This makes both the vaccines most suited for Indian conditions as most of the vaccines here are kept at the same temperature range. This also makes the transportation and storage of both vaccines easier.

EFFICACY : Both the vaccines have shown more than satisfactory results ever since the inoculation started in India. The effectiveness of the Covishield vaccine is nearly 90% as per the global reports and Covaxin’s 81% according to interim 3rd phase trial results.

SIDE EFFECTS : After injecting the vaccine, you may experience pain at the site of injection. Some people also experience side effects such as headache, joint pain, may feel like feverish. These side effects do not persist for long and generally goes within a day or two. (Acknowledgement : Pharmeasy.in)

INTERVALS BETWEEN DOSES :

COVISHIELD :   Interval between 1st and 2nd dose was initially 4 weeks.  Then it was changed o 6-8 weeks   and  on 13 May 21 it was changed to 12 to 16 weeks.  Presently following 12-16 weeks.                                                    

COVAXINE : Interval between 1st and 2nd dose is 4-6 weeks and there is no change.

MY OBSERVATION : Me and my wife have taken both the doses of Covishield vaccine (after an interval of 6 weeks) and we had no side effects except fever after First dose for me only and fever lasted for 24 hours only. My wife had pain on the site of Injection after First dose and Second dose went very smooth for both of us.

Artist’s creation

Artist’s creation

In the year of Corona, a devastated year for the migrant workers in India. Migrant workers means those workers who migrated to other states for their livelihood. Due to sudden lockdown in March 2020 due to Corona (Covid19) many lost their jobs at their working places. Later Lockdown extended and finally all type of transports like train, bus were stopped plying. They tried to return to their homes by means of any available mode with spending their all savings. Those who could not afford, they started walking for days. In the process many lives were lost forever due to hunger, accidents while travelling before reaching their homes. These uncommon sad stories are known to us. Days are passing but Corona not gone till now. Durga Puja, great festival of India, mainly for Bengalis and Dussera for all over India arrived. Festivals are being organised at low scale with all precautions like musk, sanitiser and distancing.

In connection with Durga Puja, I will show you how an artist created a master piece with the theme of migrated workers. A migrated family with little children has been imagined who survived with her children and reached to their hut and looking back to the crowd. Artist Pallab Bhowmick of Krishnanagar has taken this as theme to make his “Durga” of this year. He idolised her as Devi Durga just by putting a symbolic third eye on her forehead as we see in Goddess Durga. Goddess Durga in her hutment with bagful of relief materials in her hands instead of weapons. Her children, on her lap is depicted as Kartick, on the left is Saraswati and Laxmi on the right and forth Ganesh has been shown below.

বেহালা বড়িষা ক্লাবের প্রতিমার রাতের দৃশ্য। কৃষ্ণনগরের মৃৎশিল্পী পল্লব ভৌমিকের তৈরী। থিম – পরিযায়ী শ্রমিক পরিবার।

কৃষ্ণনগর ঘূর্ণির ভাস্কর পল্লব ভৌমিকের তৈরি একটি মূর্তি এ বছর খুব জনপ্রিয় হয়েছে। এখানে দেবী দুর্গাকে একজন পরিযায়ী শ্রমিক ও মায়ের ভূমিকায় দেখানো হয়েছে। তিনি শিশুসন্তানকে কোলে নিয়ে পিছনে ফিরে দর্শকের দিকে তাকিয়ে রয়েছেন এবং তাঁর কপালের তৃতীয় নেত্রই বলে দিচ্ছে তিনি আসলে দেবী দুর্গা।

In the making

Lockdown continues in India

On 24 March, Prime Minister ordered a nationwide lockdown for 21 days, limiting movement of the entire 1.30 billion population of India as a preventive measure against the 2020 corona virus Pandemic in India. The lockdown was ordered when the number of confirmed positive cases of corona Virus in India was approximately 500.

Observers state that the lockdown has slowed the growth rate of the pandemic by 6 April to a rate of doubling every six days, from a rate of doubling every three days earlier.

As the end of the lockdown period approached, state governments and other advisory committees recommended extending the lockdown. 

On 14 April, Prime minister Mr. Modi extended the nationwide lockdown till 3 May, with a conditional relaxation after 20 April for the regions where the spread has been contained.

Aproching roads, flyovers to Howrah bridge, are empty during lockdown.

As on 20 April 2020, death toll due to Covid 19 rose to over 500 and number of cases crossed 17,000 in the country (source : Times of India).

Lockdown India

Prime Minister of India, Mr. Modi urged, Indian Citizens to observe self-imposed Curfew (Janata Curfew) on 22nd. March 2020, Sunday from 07am to 09pm in order to slowdown spreading of Corona Virus (Covid19) among citizens. The curfew was for 14 hours only and therefore viruses will remain active even after 14 hours. Therefore, this step was not adequate to combat the spreading but, I think, it was an initiative to read the pulse of the people and take harder steps. In fact, people wanted complete lockdown India for 3 days at least. Anyway, Janata Carfew on 22nd March was successful all over India and gave a clear indication for the Lockdown. School Colleges already closed, exams stopped midway. On the evening of 22nd. March CM of West Bengal Ms. Mamata Banerjee announced complete Lockdown of Kolkata and all District towns in the state from 23rd. 5pm to 27th Mid night with some exceptions like Grocery, medicine shop etc. All offices in the state will remain closed and transports, long distance trains, inter-state bus services, domestic and international flights stopped for this period so that people should forcefully stay home.

This state was free from Corona virus till a student of Oxford returned home and being a son of a bureaucrat mother and Doctor father he did not bother to get himself admitted in the state run ID Hospital. He stayed at home and even visited a mall and mom’s Office (Secretariat called “Nabanna”). His mom is holding a high ranking post – Special Secretary to the State Home Deptt. She must have chaired several meetings on the Corona Virus too. Being such a responsible post how she could be so much ignorant and take her son to “Nabanna” the state Secretariat, CM’s Office. it is reported that she attended a meeting that day with her Boss, Home Secy. She knew that her son’s girl friend got infected in UK through an email from Oxford. College emailed two days back stating that his friend tested positive and advised to keep him isolated and get tested. But reluctantly they visited an hospital after two days and that hospital too advised them to go to ID Hospital Beleghata (Infectious diseases Hospital). But they avoided that day too. She attended a meeting in her office and her boy was accompanied by her in the same car. Next day they visited ID hospital and got tested positive. Mean time, in these 2/3 days, his father, a Doctor attended his office as well as his Chambers. Being a Child specialist, he treated many children during this period. After the boy tested positive, both parents along with their maids, drivers are in a Isolation Centre. This is an example of irresponsibility, negligence of a highly educated family.

Second case also is UK returned student who stayed in his home with his family till he came to know that two of his friends tested positive. Then he visited a doctor and finally landed at ID Hospital. His entire family members are kept in a isolation Centre.

The third case too came from abroad. A girl student from scotland came to city and she went strait to ID Hospital where she tested positive. She did not spread much except her father who went to receive her at airport and the driver only. they are in isolation for 14 days.

While writing this post, a sad news came that the 4th. case, one of our co-citizen aged about 57 years a Railway employee expired today. He attended a marriage in Bilaspur travelled back by train to Kolkata in February. Then he attended his office for 5 days. His wife so long was suspecting this train journey. His son studying in Philadelphia USA and visited India in Feb last. Doctors doubted that they are hiding some thing. Then his wife was thoroughly counselled by the treating Doctor and finally she revealed that his son and his Italian girl friend visited them (Came from Italy) in the month of February last. So this case has a strong Italy connection. But it is not clear about his son’s and his girl friend’s health. That is still to be known and may be published later. At present all of his family members and office collegues are in hospitals. Very sad that today, 23rd. Mar 2020 he expired while in Ventilation. This is the First Corona death in the city as well as in the state of west Bengal. Total death in India goes to 8 till now. What will be tomorrow’s figure we don’t know because people are not serious and irresponsible.

From the above it is clear that all the cases came from UK and Italy. Except one case, they roamed freely in the city, relatives, friends, office and we do not know how many have been infected by them. It takes about 4-5 days, to show the symptoms. And during this time, infected people thinking themselves as healthy, they lead normal life, in turn infecting numerous people. If this goes on this way, then India will enter to third stage soon which no sensible citizens, no Govt. want. This necessitated Lockdown the states. CM announced the Lockdown of Kolkata and all District towns in the state from today, 23rd. 5pm to 27th Mid night . Many states already declared or will follow and hopefully India going to be completely Lockdown soon.

Be a responsible citizen, Break the chain of spreading deadly virus. Stay Home, stay safe.
