Dr Tom Inglesby, director of the Center for Health Security at the Johns Hopkins Bloomberg School of Public Health, said on Sunday that while COVID-19 vaccines continue to prove effective against current variants, this may not continue to be the case so more variants emerge.
Inglesby downplayed concerns about the recently discovered variants, particularly the South African variant which has reportedly shown resistance to certain treatments and possibly to the vaccine itself.
“What we are seeing is that in the variant that was found in South Africa, at least in mild to moderate disease, some of the vaccine studies show reduced efficacy,” Inglesby confirmed to the host. from “Fox News Sunday” Chris Wallace, while noting that “we still have enough cushion with the vaccines that they are still very effective at this point.”

Inglesby, however, warned that “this is a message that says this virus is evolving and may continue to evolve in ways that make it more dangerous – either more transmissible or more deadly.”
Inglesby, however, praised the Johnson & Johnson vaccine, saying it was an ‘incredible’ development that provides a much needed boost as country strives to vaccinate more people in an aggressive campaign .

He also suggested that the trials for the Johnson & Johnson vaccine represented the new variants – something the earlier Pfizer and Moderna vaccines could not have been tested for – and that could have taken into account the lower efficacy of the Johnson vaccine. Johnson.
The vaccine also appears to improve its effectiveness over time, potentially achieving 85% protection against all strains after 28 days.
The vaccine could help push schools to reopen. Experts say “community prevalence” is the most important factor in determining whether or not to reopen schools, and more vaccines will help reduce this prevalence.

“As long as the prevalence of disease in the community around them is not overwhelming,” Inglesby said of the school reopening. “So this is very encouraging news, but what we are seeing is that schools that have the resources can put these things in place, and many schools across the country have not been able to put these things in place. in place.
