Mexican President Andres Manuel Lopez Obrador received the AstraZeneca dose against the coronavirus on Tuesday, calling for trust in vaccines after many countries limited the use of AstraZeneca due to suspected links to rare blood clots.

67-year-old Obrador has said the benefits of getting vaccinated outweighed the risks of the low-cost jab, which is a core pillar of Mexico’s inoculation strategy.

Ahead of rolling up his sleeve for the dose at the end of his regular daily news conference, Lopez Obrador said he wanted to urge all older adults to also receive their jabs in order to be protected from COVID-19.

“We’re sure there is no risk, no danger, that there are no serious side effects,” he said, without specifically naming the AstraZeneca vaccine.

He added that his cabinet is tracking vaccine studies being conducted worldwide.

Lopez Obrador said he would sit for 20 minutes after receiving the dose, as recommended by a healthcare worker who administered the jab to the president on live television and social media.

“It didn’t hurt,” Obrador said. “Right now I’m feeling very good.”

Earlier this month, Mexico’s health regulator said it did not plan to limit the use of the 2-dose AstraZeneca vaccine, but was examining data from Britain’s vaccine advisory committee.

The committee has said an alternative to AstraZeneca should be given to people under 30 where possible.

Mexico started its inoculation drive late last year and has so far fully vaccinated around 4 million people, most of whom are adults over 60, out of a total population of 126 million.
