The US job market appears to be responding positively to the COVID-19 vaccine rollout. However, lingering questions remain. Predominately: How long can a vaccinated person expect to be protected from coronavirus transmission? Dr.Anthony Fauci—who serves as the chief medical advisor to the president — delivered his third vaccine verdict this week.
In an interview with MSNBC’s Mehdi Hasan, Fauci said Americans may need booster shots within a year of receiving their second vaccine dose. Right now, academicians are watching case numbers closely in order to determine levels of efficacy associated with the vaccine candidates available “and when, or if, the protection diminishes.”
“We need to be careful about that six-month number. We know for sure it’s effective for six months and highly likely that it will be effective for a considerably longer period of time,” Fauci said during the chat.
“So the good news is that it’s at least six months,” Fauci said. “Hopefully a lot more. But in direct answer to your question, if it turns out a year or a year and a half, we very well may need to get booster shots to keep up the level of protection.”
Data has been somewhat complicated by new more transmissive variants. The South African strain ( 501.V2) is currently the most dominant strain in the states.
Not only is 501.V2 more contagious than other coronavirus sequences, but it also may be able to blunt the effectiveness of contact tracing—in addition to causing more severe illness.
“The emergence of new COVID-19 variants is common. However, those with a higher speed of transmission or potentially increased pathogenicity are very concerning. Crucial investigations are underway to comprehensively understand the behavior of the new mutant virus and steer response accordingly,” concluded Dr. Matshidiso Moeti, WHO’s regional director for Africa.
The vaccine doses produced by Pfizer and Moderna require two shots for full vaccination. Health systems are currently recruiting study samples to see if a third COVID-19 vaccine shot for will make initial doses effective against 501.V2.
“The trial has a total of 210 volunteers — including some who’ve not yet received any COVID-19 shot — divided into several cohorts testing different formulations. Researchers want to test the safety of the vaccine, how people’s immune systems respond and what side effects come up,” health reported, A. Pawlowski adds.
Dr. Fauci maintains that there isn’t any reason to panic about J&J’s dose considering the adverse outcomes listed above are still appreciated as very rare events.
“So if you’ve had it a month or two ago, I think you really don’t need to worry about anything. Having said that, you still want to be alert to some symptoms, such as severe headache, some difficulty in movement, or some chest discomfort and difficulty breathing,” Fauci continued.
“That’s one of the things that we want to investigate. There have been similar types of phenomena that have occurred during pregnancy. Clotting abnormalities are known in women who take birth control pills, so certainly there could be a hormonal aspect to this.”
