COVID-19 Vaccines

COVID-19 Vaccine

 

COVID-19 vaccines are now being administered to people throughout the United States. Public health officials hope much of the nation will be inoculated this year to stop the coronavirus spread. Here are answers to some frequently asked questions.

  • What vaccines are available?
  • Multiple vaccines have been authorized for use in the United States. The first was developed by the pharmaceutical firms Pfizer and BioNTech, and it consists of two shots, given three weeks apart. The second available vaccine, Moderna, was developed by a Massachusetts biotechnology company in partnership with the National Institute of Allergy and Infectious Diseases. It consists of two shots, given 28 days apart.

    U.S. regulators have approved a third vaccine, this one made by Janssen Pharmaceuticals Companies of Johnson & Johnson. It requires only a single shot and is easy to use, ship and store. Like the Pfizer and Moderna vaccines, it was proven safe and effective in extensive clinical trials. The nation’s leading medical experts urge people to take whichever coronavirus vaccine is available to them.

  • How do they work?
  • The Pfizer and Moderna vaccines employ messenger RNA technology, which has been approved by the Food and Drug Administration (FDA) for human use. The vaccines contain molecular instructions that prompt your cells to create a protein in response to a protein on the surface of the coronavirus. In that way, the vaccines prepare your immune system to ward off the virus if it should try to invade your healthy cells.

    The Johnson & Johnson vaccine works differently. It uses a harmless cold virus to deliver a gene that helps your body’s immune system recognize and respond to the coronavirus.

  • The vaccines were developed very quickly. Are they safe?
  • COVID-19 vaccines were developed in record time for explainable reasons. Modern scientific tools are much faster than older technology, and scientists around the world worked together to develop a vaccine to fight the global pandemic. The vaccines were tested in large, randomized clinical trials with tens of thousands of people of different ages, races and ethnicities, some with various medical conditions, which allowed researchers to quickly gather data and answer key questions about safety and protection. 

    All of the vaccines passed rigorous safety reviews by the FDA. The benefits of the vaccines were determined to far outweigh the harms associated with acquiring a COVID-19 infection. The Centers for Disease Control and Prevention (CDC) have several systems in place to ensure safety and to continue to collect information on people’s experiences with the vaccine.
  • Will I suffer side effects?
  • Most people do not have serious problems after being vaccinated. Your arm may be sore, red or warm to the touch where the shot was given. Some people report flu-like symptoms, such as fever, chills and headaches, especially after the second vaccine. These side effects are normal signs that your immune system is building up protection from the disease. If symptoms increase after 24-48 hours, contact your health care provider.
  •  Do some people have allergic reactions to the shot?
  • Allergic reactions to vaccinations can occur. The most serious reaction is anaphylactic, which is severe and very rare. Possible symptoms of anaphylaxis include a skin rash, nausea, vomiting, difficulty breathing and shock, generally within minutes of receiving the vaccine. Anaphylaxis can be quickly reversed with an intramuscular injection, such as epinephrine. People who have had previous severe allergic reactions to other types of vaccines should talk to a medical professional before getting the COVID-19 vaccine.
  •  Will I still need to wear a mask and socially distance after being vaccinated?
  • Yes. The vaccine does not begin to protect you immediately, and scientists are still researching whether the shot prevents people from shedding the virus and infecting others. For now, the CDC recommends vaccinated people wear a mask over their nose and mouth, avoid crowds, and stay at least six feet from others.
  •  How much will the vaccine cost?
  • The federal government is providing the vaccine at no charge to people living in the United States. However, your vaccination provider may bill your insurance company, Medicaid, or Medicare for an administration fee.
  • Sometimes workers can get vaccinated before their family members. Why? 
  • States and counties are rolling out vaccines based on the tier system which is prioritizing certain employees who are more likely to be exposed to the virus at work. For this reason, some workers may receive the vaccine before their family members. Anyone who works in agriculture is now eligible for a shot. To find out when it’s your turn to get vaccinated, register at myturn.ca.gov or call (833) 422-4255 and get notified when appointments are available in your area.
  • Who has access to the data provided when people get vaccinated? 
  • The California Department of Public Health is responsible for monitoring vaccine use, and they have a data-use agreement with the CDC. According to the agreement, California will not share information that would allow the federal government to identify an individual based on the information they are given. Information provided will include a person’s birth year, sex, and county where the vaccine was administered. Vaccine eligibility is not based on residency or immigration status.
