The COVID vaccine developed by AstraZeneca has been widely used across the world, although there are some potential and relatively rare side effects. Therefore, not everybody trusts the vaccine, but for those who choose to get it into their bodies, a leading scientist has some good news.
abcNEWS.com informs us about Sarah Gilbert’s recent statements for The Telegraph. She’s a professor at Oxford University, and she claims that immunity granted by AstraZeneca’s vaccine is doing its thing well, even when it comes to the highly contagious Delta variant of COVID.
Two doses of the vaccine will be enough for most people
Gilbert says that while the immune-compromised and the elderly may require booster shots of the vaccine, the usual two-dose regimen will provide lasting protection for most who get vaccinated for COVID.

The scientist said, as quoted by abcNEWS.com:
We will look at each situation; the immuno-compromised and elderly will receive boosters,
But I don’t think we need to boost everybody. Immunity is lasting well in the majority of people.
Some parts of the world don’t have enough access to vaccines, which Gilbert believes is a significant problem that needs to be solved. She added, as also cited by abcNEWS.com:
We need to get vaccines to countries where few of the population have been vaccinated so far,
We have to do better in this regard. The first dose has the most impact.
According to Our World in Data, only 1.9% of those people living in low-income countries have been vaccinated for COVID with at least one dose. Also, the same page tells us that 41.7% of the entire world’s population has been vaccinated for the coronavirus with at least the first dose.
