New research revealed that vaccine-induced antibodies may fade even after the double Dose of Covishield and Covaxin. This study will lead to rethinking the third booster doze into the vaccine schedule.

Considering the third wave of coronavirus, the government is planning to vaccinate all adults in the country as soon as possible. At the same time, the doctors are also saying that an antidote should be utilized. Meanwhile, a survey conducted by the Regional Medical Research Center (RMRC) in Orissa raised concerns. The study was jointly conducted by the Indian Council of Medical Research (ICMR) and Regional Medical Research Center (RMRC).

The study says that within 2 months of taking Covaxin, the body begins to lose antibodies. On the other hand, even after taking Covishield, the antibodies are starting to decrease after three months. ICMR-RMRC completes this study. The methodology of the survey will be noted by the organizations.

The survey was conducted on 614 people after vaccination on behalf of the organization. Of these, 308 received Covishield. The remaining 306 got Covishield. Of these, 533 did not have a covid infection. In their case, RBD IgG (an antibody against Covid) antibodies have decreased.

One researcher claimed that they found that covid antibodies decreased within two to four months after taking two doses of the vaccine. Experts believe that modified vaccines need to be developed first in this situation. Or need to turn on the Booster Dose. Many countries around the world are thinking of introducing booster doses. But our country is still waiting for more research or information on this. People with low immunity must take a booster dose 6-12 months after the vaccine.

What is the meaning of Booster Dose?

The people who have been vaccinated build enough protection against COVID-19 but, their immunity becomes gradually weaker, then a ‘booster dose’ can be given in such case. Just to protect the people from the deadly virus.

The Centers for Disease Control and Prevention (CDC) defines that the ‘booster dose’ as different from an additional dose of the vaccine. A third dose of the vaccine is given to people with moderate to weak immunity. The body of some people may not be able to build adequate protection against COVID-19 even after receiving the two doses of vaccine. A third dose is recommended by the CDC in those cases. People will be eligible after 8 months of having the second dose of mRNA vaccines in the US and other countries. But, India has not yet approved the booster dose so far.

It is clear from the situation or through the consequences of the study that the only vaccine is not enough for herd immunity among people. There should be another way to tackle the level of immunity, maybe some traditional ways of treatment should be introduced into life.
