Side Effects on COVID-19 Vaccination

Congratulations on taking an important step in the fight against COVID-19 by getting vaccinated!

Here are some important steps to take in the days and weeks ahead.


Watch for side effects

Anyone receiving the COVID-19 vaccination may develop a range of side effects, many of which are expected and may indicate that your body is appropriately responding to the vaccine by developing an immune response to protect you in the future. Note that these side effects may be more pronounced after the second dose of vaccine. If you experience any side effects, the chart below provides guidance on what you should do and how your experience may impact your work.


What to do if you had a severe reaction?

If you develop lightheadedness, confusion, difficulty breathing, swelling of the lips, face and/or throat, generalize rash or hives, you should call 119 for ambulance or immediately go to the nearest emergency department (likely to be Kutchan Kosei Hospital). If you experienced a severe reaction to the COVID-19 vaccine such as anaphylaxis, you should not receive the 2nd dose of your COVID-19 vaccine.

In the case you require assistance in a language other than Japanese, The Hokkaido Foreign Resident Support Center will provide translation support over the phone.

Continue to follow safety practices

COVID-19 vaccine is extremely effective to prevent serious illness and death, but they do not prevent 100 percent of infections. It will take several months for enough people to be vaccinated before we can begin to ease our reliance on basic safety practices. Therefore, we all must continue to wear appropriate personal protective equipment (PPE), wear a mask, stay at least 2 m (6 feet) apart from others whenever possible, and clean hands frequently. Following these simple steps significantly helps to reduce the spread of COVID-19 and other viral illnesses.
