Vaccines have been shown to be safe and effective at preventing disease. However, they are not 100% risk-free. In fact, there are some rare but serious side effects associated with each vaccine that can occur in up to 8% of people who receive them. These side effects include headache, nausea, dizziness, fatigue and muscle pain -- but rarely anything more serious like seizures or paralysis.

The Centers for Disease Control (CDC) recommends that all adults aged 19 through 65 years receive two doses of Tdap if they haven't had one so far; otherwise, it may not be necessary for most people who have never gotten vaccinated before. According to CDC data, there are more than 5 million cases of pertussis each year in the United States—about half occur among children under age five—and these numbers continue increasing every year as we continue moving toward eliminating this disease by 2025. In other words: We need more people vaccinated against this disease!

According to the CDC, up to 8% of people suffer shoulder pain after receiving the Pfizer vaccine, which was administered by nearly 1.5 million people in the U.S. so far. That's more than 100,000 people in total. The percentage of those who reported shoulder pain compared with those who didn't wasn't immediately available; however, a CDC spokesperson said that it would be released later today (April 26th).

This is not a few bad apples here or there; it's a very real effect that many people are experiencing. It's also incredibly common with other vaccines. In fact, this is not just the COVID vaccine that causes this reaction; it happens with all vaccines (and even some medications) and can be severe or mild in nature depending on where you are on the scale of reactions.

This is a completely normal side effect of essentially any vaccine. In fact, there are multiple cited cases of shoulder pain after flu shot within medical literature going back more than 20 years. It’s not dangerous and typically passes quickly. If you do experience this symptom and it continues for more than two weeks after your vaccination, contact your doctor.

Some percentage of people will always experience side effects from vaccines like this one, but these are almost always minor and short-term at worst. I'd much rather see millions of healthy people getting vaccinated than see millions of healthy people being infected with COVID and getting sick for weeks or months at a time with no end in sight. COVID is a virus that causes an illness similar to shingles (also known as herpes zoster). If you're vaccinated against it (which you should be), there's a good chance that you won't get sick from it—but even if you do get sick from COVID, the symptoms will likely be short-lived and milder than those associated with shingles. A small percentage of people will develop complications from their vaccinations; however, these complications are rare enough that most doctors recommend receiving all recommended vaccines regardless.

The vaccine is safe, effective and necessary for us all. COVID vaccines are the most effective way to prevent disease and protect you from getting sick. It’s also the best form of prevention for COVID. The vaccine is free from side effects because it works by mimicking natural antibodies that your body produces naturally in response to infection with CVID virus. This means that there are no adverse reactions associated with receiving this shot or any other immunization (e.g., an allergic reaction).
