Pfizer booster vaccine: 'Other' adverse side effects – including 'lymphadenopathy'

Pfizer’s booster is the same formulation and strength as the first two Covid vaccinations; it does not, however, mean you will react in the exact same way. Are you prepared for these “other” side effects? Clinical trial data, submitted to the US Food and Drug Administration (FDA), show that “other side effects” included vomiting, diarrhoea, and fever. Meanwhile, three of the “most commonly reported reactions” included: pain at the injection site, fatigue, and headache.

In fact, the report sent to the FDA on September 17, 2021, showed that 83 percent of the trial’s booster recipients reported pain at the injection site.

As for fatigue, 63.7 percent of booster recipients reported this side effect, while 48.4 percent reported a headache.

The Centres for Disease Control and Prevention (CDC) pointed out “unsolicited adverse events”.

One such unsolicited adverse event was reports of lymphadenopathy, which is “plausibly related to the vaccine”.

“And there is no basis upon which to conclude a causal relationship.”

“Serious adverse events” – defined as any “untoward medical occurrence that resulted in death”, a threat to life, or required hospitalisation – included:

  • Acute myocardial infarction
  • Cerebrovascular accident
  • Appendicitis.

“The proportions of participants who reported at least one serious adverse event were 0.4 percent in the vaccine group and 0.2 percent in the placebo group,” the CDC clarified.

As of Friday, November 5, the Government has reported that more than 9,347,074 people have now had their Covid booster jab.

From Monday, November 8, people will be able to pre-book an appointment for a booster Covid vaccine (if eligible) five months since their second dose.

Do note, however, that the appointment you will be offered will still be 182 days (six months) after your second Covid dose.

Anybody who tests positive for Covid, who is eligible for a Covid booster, must wait at least four weeks after testing positive for the disease to book their booster jab.

If applicable, people can now book their Covid vaccine boosters on the NHS website.
