JOHANNESBURG, March 3 (Reuters) – Research by South African scientists suggests that antibodies raised by exposure to the country’s dominant variant of the coronavirus may prevent infection with other variants, scientists said on Wednesday.

The results of laboratory studies give hope that COVID-19 vaccines based on the 501Y.V2 variant first identified at the end of last year could protect against several variants circulating in different parts of the world.

The more The contagious variant caused a second wave of infections in South Africa which peaked in January and is believed to have spread to many other countries in Africa and other continents.

“We used plasma… from people who were infected in this last wave with 501Y.V2 and we used it against the first wave virus… what we found was that it could neutralize himself, OK not as well as he could neutralize himself but it’s not bad at all ”, said Alex Sigal of the African Institute for Health Research news conference.

Sigal said that vaccines designed with the 501Y.V2 variant in mind “might have cross-protection with other variants, … that gives you an idea of ​​how this variant problem can be solved.”
