Vaccines continue to reduce a person’s risk of contracting the virus that causes COVID-19. Here are some important factors that might be helpful!

Vaccines continue to reduce a person’s risk of contracting the virus that causes COVID-19. Here are some important factors that might be helpful!
COVID-19 vaccination reduces the risk of COVID-19 and its potentially severe complications. All COVID-19 vaccines currently authorized for use in the United States helped protect adults and children 5 years and older against COVID-19, including severe illness, in clinical trial settings. So far, studies that have looked at how COVID-19 vaccines work in real-world conditions (vaccine effectiveness studies) have shown that these vaccines are working well.
Most vaccine effectiveness data now available are related to mRNA vaccines (Pfizer-BioNTech and Moderna) because these vaccines have been available longer. CDC and other experts continue to study the effectiveness of both mRNA vaccines and the Johnson & Johnson’s Janssen (J&J/Janssen) COVID-19 vaccine in real-world conditions.
Infection and Spread
Below Vaccination Myths are collected and circulated on the internet, and the answers are from CDC’s “Bust Common Myths and Learn the Facts”
ANS: None of the COVID-19 vaccines contain the live virus that causes COVID-19 so a COVID-19 vaccine cannot make you sick with COVID-19.
It uses the mRNA vaccines, such as Pfizer-BioNTech and Moderna, work differently than other types of vaccines, but they still trigger an immune response inside your body. This type of vaccine is new, but research and development on it has been under way for decades.
The mRNA vaccines do not contain any live viruses. Instead, they work by teaching our cells to make a harmless piece of a “spike protein,” which is found on the surface of the virus that causes COVID-19. After making the protein piece, cells display it on their surface. Our immune system then recognizes that it does not belong there and responds to get rid of it. When an immune response begins, antibodies are produced, creating the same response that happens in a natural infection.
In contrast to mRNA vaccines, many other vaccines use a piece of, or weakened version of, the germ that the vaccine protects against. This is how the measles and flu vaccines work. When a weakened or small part of the virus is introduced to your body, you make antibodies to help protect against future infection.
ANS: No. COVID-19 vaccines do not contain microchips. Vaccines are developed to fight against disease and are not administered to track your movement. Vaccines work by stimulating your immune system to produce antibodies, exactly like it would if you were exposed to the disease. After getting vaccinated, you develop immunity to that disease, without having to get the disease first.
ANS: No. Receiving a COVID-19 vaccine will not make you magnetic, including at the site of vaccination which is usually your arm. COVID-19 vaccines do not contain ingredients that can produce an electromagnetic field at the site of your injection. All COVID-19 vaccines are free from metals.
ANS: No. COVID-19 vaccines do not change or interact with your DNA in any way. Both mRNA and viral vector COVID-19 vaccines deliver instructions (genetic material) to our cells to start building protection against the virus that causes COVID-19. However, the material never enters the nucleus of the cell, which is where our DNA is kept.
ANS: Yes. COVID-19 vaccination is recommended for everyone 5 years of age or older, including people who are trying to get pregnant now or might become pregnant in the future, as well as their partners. Currently, no evidence shows that any vaccines, including COVID-19 vaccines, cause fertility problems (problems trying to get pregnant) in women or men.
ANS: Virus does not discriminate. Unfortunately, many young and healthy people have died from the COVID-19.
ANS: You should get a COVID-19 vaccine, even if you have already had COVID-19 because:
Research has not yet shown how long you are protected from getting COVID-19 again after you recover from COVID-19. Vaccination helps protect you even if you’ve already had COVID-19.
ANS: In general, people are considered fully vaccinated:
ANS: Accurate vaccine information is critical and can help stop common myths and rumors.
It can be difficult to know which sources of information you can trust. Before considering vaccine information on the Internet, check that the information comes from a credible source and is updated on a regular basis from https://www.cdc.gov/vaccines/vac-gen/evalwebs.htm
ANS: Although infected vaccinated people can spread COVID-19 to others, they are far less likely to catch COVID-19 in the first place. Breakthrough infections also tend to be contagious for a shorter period of time.
You may have some side effects, which are normal signs that your body is building protection. These side effects may affect your ability to do daily activities, but they should go away in a few days. Some people have no side effects. Below are Common Side Effects:
Pain
Tiredness
Redness
Headache
Swelling
Muscle Pain
Chills and Fever
Nausea
On the Arm where you got the shot
Rest of your Body
Even you are fully vaccinated, there are still precautions to take to maximize the protections
COVID-19 vaccines teach our immune systems how to recognize and fight the virus that causes COVID-19. It typically takes 2 weeks after vaccination for the body to build protection (immunity) against the virus that causes COVID-19. That means it is possible a person could still get COVID-19 before or just after vaccination and then get sick because the vaccine did not have enough time to build protection. People are considered fully vaccinated 2 weeks after their second dose of the Pfizer-BioNTech or Moderna COVID-19 vaccines, or 2 weeks after the single-dose Johnson & Johnson’s Janssen COVID-19 vaccine.
Some people in your family need to continue to take steps to protect themselves from COVID-19, including:
