COVID-19 Vaccine Boosters Unrequired: Top FDA, WHO Scientists

By Antonio Gozain | Wed, 09/15/2021 - 10:50

COVID-19 vaccine booster shots are unnecessary for general population due to the high efficiency of the vaccines to prevent severe disease, including the delta variant, concluded both US Food and Drug Administration (FDA) and WHO scientists in an international study published by The Lancet.

The analysis done by FDA and WHO officials concluded that the approved vaccines “continue to be highly effective against severe disease.” On average, vaccines are 95 percent successful in preventing serious illness, read the published results, and 80 percent effective in preventing infection altogether.

Although the benefits of primary COVID-19 vaccination clearly outweigh the risks, there could be risks if boosters are widely introduced too soon, or too frequently, especially with vaccines that can have immune-mediated side-effects (such as myocarditis, which is more common after the second dose of some mRNA vaccines, or Guillain-Barre syndrome, which has been associated with adenovirus-vectored COVID-19 vaccines,” warned the authors on The Lancet.

This view contrasts with the policies being considered by several governments across the world, including the US’s and the UK’s that plan to offer vaccine boosters to those fully vaccinated beginning in September. On the other hand, Israel began offering a third Pfizer-BioNTech jab earlier, concluding that “among people aged 60 and over, the protection against infection provided from 10 days after a third dose was four times higher than after two doses,” said Israel’s Ministry of Health.

WHO has repeatedly encouraged developed countries to donate vaccines to those with lagging vaccination campaigns. "Any decisions about the need for boosting or timing of boosting should be based on careful analyses of adequately controlled clinical or epidemiological data, or both, indicating a persistent and meaningful reduction in severe disease. Current vaccine supplies could save more lives if used in previously unvaccinated populations," the authors wrote.

No COVID-19 Vaccine Boosters in Mexico

President Andrés Manuel López Obrador and Deputy Minister Hugo López-Gatell have been clear regarding COVID-19 vaccines and how important it is to meet the schedule prepared in Mexico. However, while boosters are not of Mexico’s interest for the moment, over 262 children have asked local courts for legal protection to receive their shots, arguing to be at risk due to comorbidities.

Following continuous discussion, López-Gatell announced that 1 million minors between 12 and 17-years-old, considered to be in a position of risk in case of COVID-19 infection, will be vaccinated. “We have identified a million people from 12 to 17 years old with cancer (leukemia, lymphoma, solid tumors), kidney or liver failure, HIV/AIDS with organ transplants, congenital diseases and others that weaken the immune system,” said López-Gatell.
