Examples

• The higher dose shot also worked against another malaria parasite strain from Brazil, protecting six out of six people who took chloroquine and seven out of nine people given pyrimethamine.

• A low-dose vaccine with around 51,200 sporozoites followed up with chloroquine protected four out of five participants when they were exposed to the parasite three months after the last dose.

• Two or three days after the shot, vaccinated participants took one of two anti-malaria drugs — pyrimethamine and chloroquine — to weaken and eliminate the parasite.

• The agency previously granted an emergency authorization for two malaria drugs in March, but it reversed itself in June, saying the drugs, hydroxychloroquine and chloroquine, were unlikely to be effective and caused side effects on people’s hearts.

• The malaria drugs hydroxychloroquine and chloroquine have shown no benefit for infected people.
