Updated June 26, 2019 09:48:13 The flu vaccine is available at pharmacies across the country and in some areas of the country for purchase.
But there is no official count of the number of people who are vaccinated with the vaccine, nor of the effectiveness of the shot.
So, what are the risks?
In an effort to answer that question, The Washington Post is providing you with a summary of the latest information about flu shots and their effectiveness.
Here are five facts to consider: 1.
There are currently about 12 million flu shots in use in the United States.
Flu shots contain only part of the vaccine: only about 5 percent of the virus is contained in the vaccine.
The flu shot contains about 100 million inactive virus particles.
Most people who get vaccinated have received the vaccine as part of a routine medical visit.
The majority of people on average receive the flu shot within two weeks of the vaccination.
What are these risks?
Flu shots can cause serious side effects, including fever, muscle aches, cough, sore throat and abdominal pain.
They also can cause bleeding and the flu can cause pneumonia.
A study of the flu vaccine used in the trial by the Centers for Disease Control and Prevention found that people who received the flu jab had about twice as many pneumonia-causing antibodies as those who received placebo.
A third of people vaccinated had higher than normal levels of antibodies to the antibodies, and two-thirds had antibodies that were higher than those found in people who had received the placebo.
About 40 percent of people with the highest levels of antibody antibodies had pneumonia.
These high levels of immunity can make the immune system attack healthy tissue, which can cause damage and eventually lead to pneumonia.
The vaccine does not protect against most flu viruses.
Some strains of the influenza virus can cause more severe or life-threatening symptoms, including pneumonia, if the virus spreads.
Other strains, such as the seasonal flu, do not cause symptoms at all.
However, the vaccine is designed to protect against flu viruses that have been circulating in the U.S. for more than a decade, including the ones that caused the pandemic of 1918.
Some of the other flu viruses in the world that are known to cause severe or disabling illness are: H1N1, H1S1, and H7N9.
These viruses are spread by respiratory droplets.
Flu vaccines contain a high concentration of antibodies that make them highly effective against most of the viruses currently circulating.
The antibodies that are included in the flu shots contain a “reservoir” of neutralizing antibodies.
These antibodies neutralize the virus so that it can no longer infect healthy cells.
The high levels in the vaccines have been shown to reduce the severity of symptoms and help people recover more quickly from illness.
Flu vaccine effectiveness: The CDC estimates that flu vaccines have an effective effectiveness of about 92 percent against the flu.
The efficacy is not uniform.
Some studies have found higher levels of effectiveness against some strains of influenza, including H1-19, than against others.
But these studies were limited by the fact that the researchers used different flu vaccines and tested a number of different strains of flu.
Researchers are continuing to develop flu vaccine strategies that better protect against these other strains.
There is no data showing that flu shots are a reliable way to prevent influenza, and there is a growing body of research that shows that they do not protect people from getting sick.
Some people may be at increased risk of developing serious complications from flu vaccines, including kidney and liver damage, severe ear infections and pneumonia.
But even if you get sick from the flu, you may recover, especially if you take your flu shots regularly.
How often do flu shots need to be taken?
The flu shots typically are given for a period of at least two weeks, but sometimes they are given two or more times a week.
The CDC recommends that people get at least six doses in a row.
The number of doses needed for each person is determined by their age, sex, health history, and vaccination history.
Flu shot effectiveness vs. other flu vaccines: The effectiveness of flu vaccines is not equal to the effectiveness against the pandemics H1Ns and H2Ns.
Both the H2N vaccine and the H1 vaccines have shown to be effective against pandemic H1 viruses, but the effectiveness is not as high as against other pandemic viruses.
For example, the effectiveness for H1 is about 80 percent, compared with about 70 percent for the H3N2 vaccine.
For most people, the flu vaccination has no benefit against the seasonal influenza, which is one of the worst flu viruses to ever circulate.
Some flu vaccines can help prevent pneumonia.
Some are better than others at stopping flu, but many have not been shown by clinical trials to be helpful in preventing pneumonia.
