Want to know the facts about the new COVID-19 vaccines? Here's what you need to know about the different types of vaccinations and the benefits of having the vaccine.

COVID-19 Vaccines: Get the facts

Vaccines to prevent coronavirus disease 2019 (COVID-19) may be the best hope for ending the epidemic. But as the US Food and Drug Administration (FDA) continues to approve or authorize the emergency use of COVID-19 vaccines, you likely have questions. Learn about the benefits of COVID-19 vaccines, their mechanism of action, their potential side effects, and the importance of continuing to take steps to prevent infection.


Benefits of covid 19 vaccines

The COVID-19 vaccine may help:

  • Prevents you from contracting COVID-19 or from becoming seriously ill or dying from COVID-19
  • Preventing the spread of COVID-19 to others
  • The number of vaccinated community members increases against COVID-19 - which slows the spread of the disease and contributes to herd immunity (so-called herd immunity)
  • Preventing the virus that causes COVID-19 from spreading and replication, the two processes that allow it to form a mutation that may be better able to resist vaccines

Having the COVID-19 vaccine may provide some natural protection, or immunity, from re-infection with the virus that causes COVID-19. But how long this protection lasts is not known. Because re-infection is possible, and since COVID-19 can cause serious medical complications, it is best for those who have previously had COVID-19 to get the appropriate vaccine. If you received treatment for COVID-19 with monoclonal antibodies or convalescent plasma, wait 90 days before receiving the COVID-19 vaccine.


Safety and Side Effects of COVID-19 Vaccines

Currently, there are several COVID-19 vaccines undergoing clinical trials. The US Food and Drug Administration continues to evaluate the results of these trials before approving or licensing the use of Covid-19 vaccines. But due to the urgent need for COVID-19 vaccines, and because the FDA approval process can take anywhere from several months to several years, the FDA initially issued an emergency use authorization for COVID-19 vaccines based on less data than is usually required. Data must show that vaccines are safe and effective before the FDA can issue an emergency use approval or authorization. Vaccines with FDA approval or emergency use authorization include:

  • Pfizer-Bioentiq vaccine for COVID-19. The US Food and Drug Administration has approved the Pfizer-Bioentiq vaccine, now called Comirnaty, to prevent COVID-19 in people 16 years of age and older. The U.S. Food and Drug Administration approved the Comirnaty vaccine after data found it to be safe and effective. The Pfizer-Biointech vaccine is 91% effective in preventing symptoms of COVID-19 infection in people 16 years of age and older.
  • The vaccine is still subject to an emergency use authorization for children ages 12 to 15. The vaccine is 100% effective in preventing COVID-19 in children aged 12 to 15 years. It requires two injections, 21 days apart. The second dose may be given up to six weeks after the first dose if needed.
  • Moderna Vaccine for Covid 19. The Covid 19 vaccine produced by Moderna is 94% effective in preventing symptoms of Covid 19. This vaccine is approved for use in persons 18 years of age and over. It takes two injections 28 days apart. The second dose may be given up to six weeks after the first dose if needed.

Janssen/Johnson & Johnson COVID-19 vaccine. In clinical trials, this vaccine was 66% effective in preventing symptomatic COVID-19 infection, 14 days after vaccination. The vaccine was also 85% effective in preventing severe COVID-19, at least 28 days after receiving the vaccine. This vaccine is licensed for persons 18 years of age and over. It requires one injection. The US Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) have recommended continued use of this vaccine in the United States because its benefits outweigh its risks. If you take this vaccine, you should be educated about the potential risks and possible symptoms of a problem involving blood clotting.

Both Pfizer-Bioentek and Moderna use messenger RNA (mRNA) in their COVID-19 vaccines. On the surface of coronaviruses are spike-shaped entities called the S protein. COVID-19 vaccines based on messenger RNA give cells instructions on how to make a harmless portion of One of the S. proteins. After vaccination, cells begin to make protein fragments and present them on cell surfaces. The immune system will recognize this protein, and it will begin to mount an immune response and make antibodies.


The Jansen/Johnsen & Johnson vaccine for COVID-19 is a vaccine that uses vector technology. In this type of vaccine, scientists take material from the Covid-19 virus and insert it into a different type of live attenuated virus, such as adenovirus. When the weakened virus (viral vector) gets into your cells, it delivers a substance from the Covid-19 virus that gives your cells instructions to make copies of the S protein. Once the cells display S proteins on their surfaces, the immune system responds by creating antibodies and defensive white blood cells. If you become infected with the virus that causes COVID-19, the antibodies will fight the virus.

Viral vector vaccines cannot cause infection with either COVID-19 or the vector virus. Also, the material the carrier delivers will not become part of your DNA.


Things to know before receiving the COVID-19 vaccine

In the United States, the federal government offers COVID-19 vaccines free of charge to all residents, regardless of immigrant legal status or health insurance coverage. COVID-19 vaccines are free whether provided by a clinic, retail pharmacy, or other location.

Yes, if you have an existing health condition, you can get the COVID-19 vaccine — as long as you haven't previously had an allergic reaction to the first dose of a COVID-19 vaccine or any of its ingredients. However, information is limited about the safety of COVID-19 vaccines for people with compromised immune systems or autoimmune diseases.

Also, COVID-19 vaccines may not provide complete protection against COVID-19 for people with weakened immune systems, whether the weakening is caused by HIV infection, certain medical conditions, or certain medications. It may be necessary to continue to follow sanitary precautions.

Taking over-the-counter pain relievers before getting the COVID-19 vaccine to prevent potential discomfort is not recommended by doctors. It is unclear how these drugs affect the effectiveness of vaccines. However, it is OK to take this type of medication after getting the COVID-19 vaccine, as long as there is no other medical reason to prevent it.

The COVID-19 vaccine is not currently available for children under 12 years of age. Clinical trials in younger children are currently underway.

Allergic reactions and covid-19 vaccines

You may have an allergic reaction to the COVID-19 vaccine if you feel the following signs within four hours after receiving the vaccine:

  • Skin rash
  • Swelling of the lips, eyes, or tongue
  • chest wheezing

If you have any signs of an allergic reaction, seek help immediately. Tell your doctor about your allergic reaction, even if it goes away on its own or if you don't get emergency care. This reaction may mean that you are allergic to the vaccine. You may not be able to get a second dose of the same vaccine. However, you may be able to get a different type of vaccine when you take the second dose.


Pregnancy, breast-feeding and fertility with COVID-19 vaccines

Experts recommend that you get the COVID-19 vaccine if you are pregnant or breastfeeding. Getting vaccinated can protect you from getting very sick from COVID-19. The antibodies that pregnant women develop when they get the vaccine may protect their babies, too.

COVID-19 vaccines do not cause infection with the COVID-19 virus, including in pregnant women or their infants. None of the COVID-19 vaccines contain the live virus that causes COVID-19.

Although more research is needed, early results indicate that taking the Covid-19 vaccine with a combination of messenger RNA (mRNA) during pregnancy does not pose significant risks to either the woman or her fetus. These findings are based on data from the US Centers for Disease Control and Prevention (CDC) Coronavirus Vaccine Safety Monitoring System. It's also worth noting that COVID-19 vaccines do not alter your DNA.

In addition, pregnant women at all three stages of pregnancy were given vaccines using the same viral vectors found in the Janssen/Johnson & Johnson COVID-19 vaccine during clinical trials. No adverse effects were shown.

If you have concerns, we recommend that you consult your doctor regarding the risks and benefits associated with the COVID-19 vaccine.

It is also recommended that you get the COVID-19 vaccine if you are trying to get pregnant or expect to become pregnant in the future. There is no evidence that any of the COVID-19 vaccines cause fertility problems.

A small number of women reported temporary changes in their menstrual cycle after receiving the COVID-19 vaccine. A small study also showed that some women had temporary changes in their menstrual cycle after contracting COVID-19. It is not clear whether it was COVID-19 itself or the vaccine against it. is the cause of these changes. More research is still needed.

Keep in mind that several things can affect your menstrual cycle, including infections, stress, sleep problems, and changes in diet or exercise.
