 And Brazil's federal government has suspended the vaccination of pregnant women with the AstraZeneca COVID-19 shot after an expectant mother in Rio de Janeiro died from a stroke possibly related to the inoculation. Coordinator of the Health Ministry's vaccination programme, Franciel Francinato, told reporters the suspension was enacted as a precautionary measure after health regulator Anvesa issued a warning about the vaccines used in pregnant women earlier in the day. Authorities are investigating the incident. The suspension applies only to AstraZeneca's shot and not to vaccines developed by Sinovac and Pfizer that have also been used in the country.
