Why do I and my children need to get vaccinated?

Vaccination protects us from many dangerous pathogens. They save lives, protect future generations and even help reduce antibiotic use and antibiotic resistance.

Are vaccines safe?

Yes. Millions of children and adults safely receive vaccines each year. Before any new vaccine is given to people it is thoroughly reviewed by health experts.

How do vaccines work?

Vaccines contain weakened or inactive parts of a particular organism (antigen) that triggers an immune response within the body. Vaccines work by stimulating a response from the immune system to a virus or bacterium. This creates a ‘memory’ in the immune system.

Don’t infants have natural immunity? Isn’t natural immunity better than the kind from vaccines?

Babies may get some temporary immunity from mom during pregnancy, adults may get the same after recovering from one particular disease, but these antibodies do not last long, leaving you or your baby vulnerable to disease.

Do I have to vaccinate my baby on schedule if I'm breastfeeding?

Yes. Breast milk does not protect children against all diseases.

What are the side effects of the vaccines?

Most vaccine side effects are very minor, like soreness where the shot was given, fussiness, or a low-grade fever. These typically only last a couple of days and are treatable.

Is there a link between vaccines and Autism?

No. Studies show that MMR vaccine is not a cause of Autism.

Why do vaccines start so early?

We vaccinate children early because they are susceptible to diseases with highest risks of complications at a young age.

Why are so many doses needed for each vaccine?

Getting every dose of each vaccine provides you and your child with the best protection. Depending on the vaccine, one may need more than one dose.

What do you think of delaying some vaccines or following a nonstandard schedule?

Every time you do not follow the schedule, you leave you or your baby vulnerable to disease. It’s really best to stay on schedule.

 The COVID-19 vaccine will affect a woman’s fertility.

COVID vaccine does not affect fertility. 

 I’ve had COVID-19, so I don’t need a vaccine.

Unfortunately, reinfection can occur even if you have previously contacted the virus. Vaccination will protect you from getting seriously ill.

 The COVID-19 vaccine development was rushed, so it may not be effective.

 All types of available vaccines were tested in hundreds of thousands of people in clinical trials and rigorously evaluated for their safety and effectiveness.

 Vaccines have a microchip that will track and control an individual.

 This is simply a conspiracy theory, that has been propagated by anti-vaxxers.

 Can a vaccine make me sick with a disease?

 It's impossible to get the disease from any vaccine made with dead (killed) bacteria or viruses or just part of the bacteria or virus.

Do vaccines cause SIDS, Multiple Sclerosis, or other problems?

Studies have not shown any connection between vaccines and these conditions.

How long does immunity last after getting a vaccine?

 A few vaccines, like the two for measles or the series for hepatitis B, may make you immune for your entire life. Others, like Tetanus, last for many years but require periodic shots (boosters) for continued protection against the disease.

 Can vaccines overload my baby’s immune system?

Vaccines help us fight infections by introducing a small number of antigens into their bodies. Antigens are parts of germs that cause babies’ immune systems to go to work. Vaccines contain only a tiny fraction of the antigens that we encounter in our environment every day.

Is it true that they use cells from aborted tissue to make vaccines?

No, nowadays vaccines usually don't have cells from aborted tissue. It's important to note that using such cells was more common in the past, but as time has passed and vaccine technology has developed, the production of vaccines has changed. Modern vaccines go through strict and ethical development processes, and most of them don't depend on cells obtained from aborted embryos.
