Sergio Perez and Carlos Sainz have accepted an offer from the Bahrain International Circuit to receive the Covid-19 vaccine.
Perez has already contracted the virus, missing both Silverstone-held races last season when self-isolating following his positive test after he travelled to Mexico between races.
"We got offered and I took the decision to take it," Perez said. "For me, back in Mexico, I don't know when I would have been able to get it. It was really nice of Bahrain to offer it to us and yeah, I took it myself."
Sainz added: "I did take it. I think it was a great opportunity and I am obviously thankful to the Bahraini government for offering it to so many people that are travelling around the world. I am happy with it."
McLaren driver Lando Norris is one of a number of drivers who had tested positive for Covid-19 during the off-season and was more reserved than his counterparts over his decision to take the offer or not.
"For us, it is a decision yet to be made, really," Norris explained. "It is obviously a private thing for my team and for myself but for now, I am healthy."
