The results showed that blood samples taken from a group of British volunteers given a dose of the vaccine produced both antibodies and ‘killer T cells. “.

It is said that antibodies can wear off, but T cells can remain in circulation for years.

The newspaper was told that while the results look promising, it has not been proven to provide lasting immunity against COVID-19.

“When you are dealing with vaccines, you cannot guarantee things, but you can say, based on the science and the way things are going, that I am cautiously optimistic that we will be able to reach this projection that we did months ago “. said Dr Anthony Fauci, the country’s leading infectious disease specialist. “No one is guaranteeing, but I’m optimistic that we will have a vaccine, one or more, that we can start distributing to people. ”

AstraZeneca, the drug maker, has signed an agreement to produce two billion doses if the trials are successful.

The vaccine could be available as early as October if all goes well.
