The coronavirus vaccines are surrounded by lots of rumours and controversies. For a while now, people have been wondering whether a third shot will be necessary this fall.
CNBC noted that AstraZeneca is not yet sure whether a third dose of its Covid-19 vaccine will be necessary for continued protection against the virus, CEO Pascal Soriot told CNBC on Thursday, as reported by CNBC.
Soriot told “Squawk Box Europe” that the company did not have a “precise answer” on whether booster shots would be needed.
Here’s what he explained:
“There are two dimensions to this immunity — antibodies [which] decline over time, but the second, very important dimension of vaccination is the so-called T-cells. They tend to protect people against severe disease, but they also provide durability.”
He continued and said the following:
“With the technology we use, we have very high production of T-cells. We’re hoping we can have a durable vaccine that protects for a long period of time. So whether we will need a third booster or not is not clear yet, only time will tell.”
