There are two new vaccines licensed for use during the 2020 -2021 flu season. The first is a quadrivalent high-dose vaccine licensed for use in adults 65 years and older. This vaccine will replace the previously licensed trivalent high-dose vaccine.
There are sufficient quantities of funded vaccine available for all persons who are eligible. NSW Health will update providers when the expected delivery date is known. Important changes to the ordering of funded influenza vaccines in 2021 are detailed below.
CDC’s influenza vaccination coverage reports show that overall flu vaccination coverage (among people 6 months and older) during 2019- 2020 increased from the previous season to nearly 52%.
Are all influenza vaccines the same? All influenza vaccines contain antigen derived from the same influenza viruses, with the one difference being that trivalent vaccines have 3 different antigens and quadrivalent vaccines have four different antigens (the same three that are in the trivalent vaccines, plus one more).
In the United States, flu season occurs in the fall and winter. While influenza viruses circulate year-round, most of the time flu activity peaks between December and February, but activity can last as late as May.
While it is suggested to get your shot before the flu season because it takes up to two weeks for your body to create the antibodies, you can get the flu later in the season. The answer? No, it’s not too late. “In the northern hemisphere, the CDC recommends getting vaccinated between early September and late October.
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.
How long does immunity from influenza vaccine last? Protection from influenza vaccine is thought to persist for at least 6 months. Protection declines over time because of waning antibody levels and because of changes in circulating influenza viruses from year to year.
The Centers for Disease Control and Prevention (CDC) recommends getting vaccinated in September or October, because the antibodies in the flu shot take two weeks to develop. The AAP also released guidelines stating that everyone 6 months and older should get a flu shot before the end of October.
Some possible downsides to flu shots include: only about 40–60% of flu shots are effective in preventing the flu each year. they can take up to 2 weeks to start working. sometimes, they cause mild side effects, such as pain, redness, and swelling at the injection site.
For the 2020- 2021 flu season, the Advisory Committee on Immunization Practices (ACIP) recommends annual influenza ( flu ) vaccination for everyone 6 months and older with any licensed, influenza vaccine that is appropriate for the recipient’s age and health status, including inactivated influenza vaccine (IIV),
CDC recommends that people get a flu vaccine by the end of October. However, getting vaccinated early (for example, in July or August ) is likely to be associated with reduced protection against flu infection later in the flu season, particularly among older adults.
In response to a regular flu shot, older people produce 50% to 75% fewer antibodies, which protect against the vaccine antigens, than do younger adults. Studies have found higher antibody levels in older adults who received high-dose flu vaccines than in those who received standard flu vaccines.
