    As of the end of June 2021, 5.4M people in Malaysia have received their first vaccine dose since the vaccination rollout in February. We are far but steadily on the path towards achieving a vaccination rate of at least 70% of the nation's population, which will mark life returning to normalcy after a painful battle against the global pandemic.
    With more and more Malaysians getting vaccinated in the recent months, we've prepared a special guide on things to note when you prepare for your vaccination (whether it's Pfizer, Sinovac, or AstraZeneca), with a focus on vaccine side effects that you can expect, including severe ones that require extra monitoring!

    Who Are More Prone To Vaccine Side Effects?

    It has been highlighted that side effects are more commonly observed among people under the age of 55 years (and those under the age of 65 for the AstraZeneca vaccine). Based on studies, those who obtain the Pfizer-BioNTech vaccine commonly report symptoms after their second dose while those who've gotten the Sinovac and AstraZeneca vaccine have a higher tendency to face side effects after their first dose.

    Common Vaccine Side Effects

    Do note that side effects are common upon getting vaccinated - in fact, these side effects are proof that your body is building immunity and typically only last for a couple of days. It is important to note that they also vary based on individuals and should not be of huge concern.
    Common vaccine side effects:
    • Pain, swelling, & tenderness at the injection site
    • Fatigue
    • Headache
    • Joint pains
    • Fever and chills
    • Flu-like symptoms
    • Decreased appetite
    For those who have work the next day, you are encouraged to notify your superior about your appointment in case you'll need to apply for a day off the following day!
    #KlookTip: To reduce pain and discomfort on your injection site, you can apply a clean, cool, and wet washcloth over it. You may also take over-the-counter medicines such as panadol to relieve post-vaccination side effects (p/s: it is not recommended to take these medicines before your vaccination - only take it after if you're feeling unwell!).

    What About The Risk Of Blood Clots With The AstraZeneca Vaccine?

    The risk of developing rare but potentially life-threatening blood clots known as thrombosis with thrombocytopenia syndrome (TTS) has been a global concern when it comes to the AstraZeneca vaccine. However, health regulators have emphasized that TTS is a possible yet extremely rare side effect, reported only in approximately 9.3 cases per million doses of the AstraZeneca vaccine.
    Most cases of the syndrome have been seen between 4 days to a few weeks after the AstraZeneca jab, so you are recommended to observe your side effects for up to a month and seek medical attention promptly if you observe any of the above severe side effects. The quicker a case is identified, the higher your chance of getting treated (according to a report by BBC, current evidence shows that 75% of people survive from the life-threatening syndrome).

    How Long Do You Need To Monitor Your Side Effects?

    Based on research, vaccine side effects commonly appear the day after your vaccination and subsequently resolve over the next few days. Most people report feeling much better after resting for a full day after their vaccination. As mentioned above, you are recommended to keep observing your side effects for up to a month just to be safe!
