But it wasn't until 1945 - nearly three decades later - that the first flu vaccine was licensed for civilian use in the U.S. In contrast, an effective and safe COVID-19 vaccine was developed in less than a year. Historically, vaccines have taken years to make it to distribution.

That said, are flu shots FDA approved every year?
Flu viruses can change from year to year, so the vaccine is updated every year to protect against new flu virus strains that are expected to circulate in the United States. The FDA plays a key role in making sure flu vaccines are safe, effective, and of high quality.
As well, will the vaccine end the pandemic? “The short answer is yes,” says Saju Mathew, M.D., a Piedmont primary care physician. “The long answer is that unless 85% of Americans get the vaccine, we are not even going to get close to ending the pandemic.”
Along, how many Nzers died 1918 flu?
The lethal influenza pandemic that struck New Zealand between October and December 1918 killed about 9000 people in two months.

For the 2019-2020 flu season, CDC is offering additional guidance on timing of flu vaccination for both adults and children. Like last season, CDC and ACIP recommend that vaccination be offered by the end of October.
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-dose flu vaccines.
Estimates of their overall immunity remain low enough that there is still a risk of significant waves of disease. Recent projections suggest that it is likely to take until late 2022 or early 2023 for these countries to achieve high vaccine coverage.
In 1917 and early 1918, the H1N1 strain of influenza swept the world, reaching New Zealand in early summer. It was carried home by soldiers returning from Europe at the end of the First World War.
But how did the deadliest pandemic ever recorded come to an end? Over time, those who contracted the virus developed an immunity to the novel strand of influenza, and life returned to normal by the early 1920s, according to historians and medical experts.
In February 1957, a new influenza A (H2N2) virus emerged in East Asia, triggering a pandemic (“Asian Flu”). This H2N2 virus was comprised of three different genes from an H2N2 virus that originated from an avian influenza A virus, including the H2 hemagglutinin and the N2 neuraminidase genes.
Influenza vaccines Four NIP vaccines will be available in 2021: Vaxigrip Tetra® and Fluarix Tetra® for eligible people aged 6 months to 64 years.
When are influenza vaccines available? Seasonal influenza vaccines under the NIP are expected to be available from April 2021.
After receiving emergency use authorization from the Food and Drug Administration (FDA) and recommendation from the Centers for Disease Control and Prevention (CDC), Johnson & Johnson-owned Janssen Pharmaceuticals became the third company to make its coronavirus vaccine available in the country
No. None of the authorized COVID-19 vaccines in the United States contain the live virus that causes COVID-19. This means that a COVID-19 vaccine cannot make you sick with COVID-19. COVID-19 vaccines teach our immune systems how to recognize and fight the virus that causes COVID-19.
Fluzone High-Dose Quadrivalent is the only licensed high-dose inactivated influenza (flu) vaccine; it is manufactured by Sanofi Pasteur Inc. Fluzone High-Dose Quadrivalent is a four-component (quadrivalent) flu vaccine approved for people 65 years and older.
Each 2021-2022 vaccine includes: Two type A flu viruses (H1N1 and H3N2) Two type B viruses (Victoria and Yamagata lineages)...The best flu vaccine for people over 65
- Fluzone High-Dose Quadrivalent — also known as the “high-dose flu shot”
- Fluad Quadrivalent.
- Flublok Quadrivalent.
High Dose and Adjuvanted Flu Vaccine Side Effects Side effects can include pain, redness or swelling at the injection site, headache, muscle ache and malaise, and typically resolve with 1 to 3 days.
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.
Research shows many individuals who recover from COVID-19 may continue testing positive for the virus for weeks to months, despite no longer being contagious.
When an infection or vaccination occurs, some of them will metamorphose into specialised antibody-production factories, known as plasma cells. Antibodies are proteins, and like any other protein will be naturally broken down and removed from the body within a few months at most.
Unpacking The “Spanish Flu” Mortality Numbers The 675,000 deaths attributed to the influenza epidemic made up 0.64 percent of the total population, a little more than six in every thousand people.

|3||Plague of Justinian||541–549|
|4||HIV/AIDS global epidemic||1981–present|
The 1957–1958 Asian flu pandemic was a global pandemic of influenza A virus subtype H2N2 that originated in Guizhou in southern China. The number of deaths caused by the 1957–1958 pandemic is estimated between one and four million worldwide, making it one of the deadliest pandemics in history.
The theory, he said, was that the infected population develops "some degree of herd immunity" to the existing virus, which then undergoes a minor genetic change that allows it to recirculate and reinfect the population. But critical to the theory of "waves" is a "pause" in infections, where the virus dies down.
