With the COVID-19 vaccine specifically, patients typically experience pain, redness and swelling in the arm where they get the vaccine. Side effects from the second shot are also typically more noticeable.

The side effects from COVID-19 vaccination, such as tiredness, headache, or chills, may affect your ability to do daily activities, but they should go away in a few days. Learn more about what to expect after getting vaccinated.

If you get a COVID-19 vaccine and you think you might be having a severe allergic reaction after leaving the vaccination site, seek immediate medical care by calling 911.

The most common serious adverse events in the vaccine group which were numerically higher than in the placebo group were appendicitis (7 in vaccine vs 2 in placebo), acute myocardial infarction (3 vs 0), and cerebrovascular accident (3 vs 1).

Most people who’ve recovered from COVID-19 have antibodies against the virus. But there’s no evidence that this will protect them if they’re exposed to it again. A study in the United Kingdom found that most people who had COVID-19 lost their antibodies within a few months.

CDC, USDA, state public health and animal health officials, and academic partners are working in some states to conduct active surveillance (proactive testing) of SARS-CoV-2 in pets, including cats, dogs, and other small mammals, that had contact with a person with COVID-19.

If soap and water are not readily available, use a hand sanitizer that contains at least 60% alcohol. Cover all surfaces of your hands and rub them together until they feel dry. Avoid touching your eyes, nose, and mouth with unwashed hands.

FDA recommends that consumers do not make their own hand sanitizer. If made incorrectly, hand sanitizer can be ineffective, and there have been reports of skin burns from homemade hand sanitizer. The agency lacks verifiable information on the methods being used to prepare hand sanitizer at home and whether they are safe for use on human skin.

• Unplug the device before cleaning.
• Use a lint-free cloth slightly dampened with soap and water.
• Don’t spray cleaners directly onto the device.
• Avoid aerosol sprays and cleaning solutions that contain bleach or abrasives.

• An infected person can spread COVID-19 starting 48 hours (or 2 days) before the person has any symptoms or tests positive.

COVID-19 spreads mainly among people who are in close contact (within about 6 feet) for a prolonged period. Spread happens when an infected person coughs, sneezes, or talks, and droplets from their mouth or nose are launched into the air and land in the mouths or noses of people nearby.The droplets can also be inhaled into the lungs. Recent studies indicate that people who are infected but do not have symptoms likely also play a role in the spread of COVID-19.
