While the rate of Covid-19 nationwide infections are slowing, health systems in parts of the country grapple with hospital wings always filled with patients. In Montana, the state faces new records of hospitalizations for coronavirus this week, with 510 active cases displayed on the dashboard site . This overshadows the peak reached in November, before vaccines were readily available, according to data from the Covid Tracking Project.

Alabama, Georgia, Kentucky, New Mexico and Texas have 15% or less of their critical care capacity available for Covid-19 and non-Covid- 19 patients, according to HHS data. Idaho and Montana are two of 15 states that have not yet fully vaccinated at least half of all residents, according to the data from US centers for monitoring and disease prevention.

A preprint from a National Institutes of Health study, which has not yet been peer-reviewed or published, suggests that mixing boosters in different combinations among the three vaccines produced a robust immune response. The most important takeaways are two things. One is that all of these nine different combinations are safe, as in there are no new or different side effects, so all of them seem to be free. danger, CNN medical analyst and emergency room doctor Dr Leana Wen told CNN's Anderson Cooper on Wednesday. The second big point to remember is that all of these combinations induced a fairly strong and robust antibody response.So in fact justifies the mix-and-match approach, she said. Moderna's candidacy will be considered Thursday and Johnson & Johnson's is scheduled for Friday. Discussion members of the FDA's Vaccines and Related Biologics Advisory Committee, or VRBPAC, will then turn to mix-and-match boosters.
