But it could have been a lot worse. Yes, there are breakthrough cases - people who have been vaccinated and still gotten COVID - but when they occur, vaccinated patients generally experience milder symptoms. First came the alpha variant, first detected in the United Kingdom, that was more transmissible and caused the surges . But there is no evidence so far that the standard prevention strategies, including vaccination, masking, distancing, ventilation and hand-washing are not effective in reducing the risk of infection or transmission., For omicron, there are very limited data on this, Bollinger says. These small differences, or variants, have been studied and identified since the beginning of the pandemic. CDC is working with many public health officials and partners to monitor all variants.
