Mexico had an uncontrolled epidemic of Covid, until the vaccine came available. As soon as the shots were available, nearly everyone got one. They also locked down the country for a month until the vaccine arrived. It wasn't the mrna vaccine either. Within around 3 months (once all adults had the shots), the epidemic was over, while it was still raged for another year in the US. In fact, the only people spreading the covid were children because the vaccines took a lot longer to approve for them. They kept them out of school, but they still went to parties! Fortunately the kids were pretty resistant and all the adults were vaccinated and the only people complaining about all this were the few Mexicans who followed Fox News or whatever lies they could stuff into their feeble brains. Even sick tourists visited Cabo, (yes they stayed open after the first month lockdown). But the virus didn't spread cause they had achieved herd immunity. Ultimately more than 90% of the population were innoculated. They trust their government and believe in medicine, which is FREE to the poor in Mexico, a Socialist Country. Likewise the Covid tests and vaccines were free to all including tourists.
