According to the World Health Organization (WHO), there is “no need” for a booster dose of Covishield or any other vaccine. Even though vaccination drives have increased worldwide, the vaccines we have are not effective against mutant strains of the SARS-COV-2 virus.
“At the moment, there is no evidence indicating a need for doses after an individual has received two doses,” stated the interim recommendations by WHO for use of the ChAdOx1-S (recombinant) vaccine known as Covishield in India manufactured by Serum Institute of India (SII).
Many countries are considering separate Covid-19 vaccines for second doses or booster shots. The interim guidance is base on the Strategic Advisory Group of Experts (SAGE). It was updated on April 21, 2021, and July 30, 2021. According to WHO, the need for booster dose will determine only when more data is available.
The vaccination drive has completed vaccinating more than 10% of the population in India. Thus, discussion increases if there is a need for a booster shot after all? This is at a time when a quarter of the 940 million people has received only one dose.
On January 16, 2021, India launched a covid-19 vaccination campaign. Covaxin and Covishield are the two vaccines that are being used for vaccination. So far, the majority of doses in India have been of the SII-manufactured Covishield.
Although, people have taken the booster dose in some states, however, the central government has requested states to stop the “irresponsible” practice of wasting immediately. After the vaccination, immunity develops through antibodies. The invisible immunity T-Cells, which have an impact on memory loss in the body. As a result, having antibodies is not the only indicator of our body’s immunity power.
