Report Side Effects Vaccine Information Leaflets

Posted on 29th April, 2021


As with any new medicine in the UK COVID19 vaccines should be closely monitored... You can help by reporting ANY side effects you may get to the government's Yellow Card System.


Some COVID19 vaccinations are 'authorised for emergency use' but not 'licenced', and so are still considered trial drugs. The UK government advises, "... if you experience any of the following from around 4 days to 4 weeks after vaccination you should seek medical advice urgently.

  • a new, severe headache which is not helped by usual painkillers or is getting worse
  • a headache which seems worse when lying down or bending over or
  • an unusual headache that may be accompanied by: – blurred vision, nausea and vomiting – diffculty with your speech – weakness, drowsiness or seizures
  • new, unexplained pinprick bruising or bleeding
  • shortness of breath, chest pain, leg swelling or persistent abdominal pain" (MAR21 p5)

You should be given a leaflet before you are given your jab, similar to this AstraZeneca leaflet, which states: [Also see BioNTech/Pfizer leaflet given at Weston-super-Mare Winter Gardens Vaccination Centre -24JUN21 - Comirnaty/Pfizer leafllet NB neither mention trial end dates? PfizerAstraZenecaandJohnson & Johnson end 2023, Moderna ends 2022]

Reporting of side effects. As with any new medicine in the UK this product will be closely monitored to allow quick identification of new safety information. You can help by reporting anyside effects you may get ...


lf you get any side effects, talk to your doctor, pharmacist or nurse. This includes any possible side effects not listed in this leaflet.


lf you are concerned about a side-effect it can be reported directly via the Coronavirus Yellow Card reporting site or search for MHRA Yellow Card in the Google Play or Apple App Store and include the vaccine brand and batch/Lot number if available.


By reporting side effects you can help provide more information on the safety of this vaccine."

As of 14 April 2021 the UK government Yellow Card system reported 693,257 vaccine reactions and 973 deaths. [As of 09 June 2021 949,286 reactions and 1,332 deaths - Updated Interactive Information found here]


Govt states, "Don’t wait for someone else to report it It is estimated that only 10% of serious reactions and between 2 and 4% of non-serious reactions are reported. Under-reporting coupled with a decline in reporting makes it especially important to report all suspicions of adverse drug reactions to the Yellow Card Scheme." (17MAY2019 - PDF)


29JUN21 - "Young people using social media to bypass vaccination rules"

"Vaccine walk-in centres are defying official guidance by handing out second doses after just 21 days. Young people in particular are bypassing the booking system and relying on word of mouth via social media to identify centres willing to bend the rules." Newscon (PDF), Telegraph (PDF)
