OAXACA, Oax. (October 2, 2020) .- With 658 thousand 549 free doses of influenza vaccine, the immunization period began in Oaxaca, which will culminate in March 2021, with the precedent that in the 2019-2020 seasonal season 113 cases were counted in the state, of which eight died.
During the 2019-2020 seasonal season, which runs from October 2019 to March 2020, the Department of Epidemiological Surveillance of the Oaxaca Health Services registered 113 cases of influenza in Oaxaca, of which 38 were AH1N1, 36 of type B, 34 of H3N2, four of seasonal influenza A and one not typified; of that total, there were eight deaths, in which 100% had not been vaccinated.
How effective the 2020 flu shot is likely won’t be known until later in the season, once it’s had time to do its thing. A Centers for Disease Control and Prevention study in 2019 found that the vaccine that year was 39% effective for all age groups, and 42% effective for people over 50.
The flu shot offers protection against the flu for about 6 months. A person should get a flu shot every year, and the best time to get one is the end of October.
Specialists say the best time to get the shot is in early September and no later than late October. If you don’t get it early, getting a flu shot later still helps. Vaccination earlier may cause protection to weaken by end of the season.
