Brazil sees one-dose, unfrozen vaccine as ideal for COVID-19 -official - (This is Money via NewsPoints Desk)

  • A senior Brazilian health ministry official said the ideal vaccine to immunize the country against COVID-19 would be one that could be stored at temperatures of a regular refrigerator and does not require multiple doses, as reported in This is Money.

  • "Ideally it would be made in a single dose," said Health Surveillance Secretary Arnaldo Medeiros, although he acknowledged that was probably not possible.

  • Medeiros noted that Brazil's cold chain lacks the ultra-frozen capacity of wealthier countries, and that would rule out the vaccine developed by Pfizer/BioNTech, which needs to be transported and stored at -70 degrees Celsius and given in two doses about a month apart.

  • Meanwhile, Moderna's two-dose vaccine uses a similar technology as Pfizer's, but can be stored at the more convenient temperature between 2 degrees and 8 degrees Celsius.

  • Among the vaccines Brazil is considering for eventual purchase, the only single-dose option is one being developed by Johnson & Johnson.

  • The news source said Brazil has an agreement with AstraZeneca to buy and produce a two-dose vaccine it is developing with Oxford University that can be easily transported and stored at normal fridge temperatures. It would be made in Brazil by the government's Fiocruz biomedical center.
