Undesirable post-vaccination readings after vaccination for COVID-19 in Poland are 0.05 percent. vaccinations, i.e. only a fraction of all injections - these are the conclusions of the latest report presented by the National Institute of Public He alth - National Institute of Hygiene. The report also shows that heavy NOPs account for 3.5 percent. all post-vaccination reactions following COVID-19 vaccination.
A vaccine adverse event is a vaccine-related deterioration of he alth that can occur up to 4 weeks after vaccination (except for tuberculosis vaccine for which this time may be significantly longer). These reactions can be mild, serious or severe. Serious reactions include, among others, pain, tenderness, impaired mobility of the vaccinated limb, fever, abdominal pain and nausea, bradycardia or weakness.
In turn, heavy reactions include, among others, neurological reactions, such as stroke, limb paresis or non-febrile convulsions, cardiological reactions, including sudden cardiac arrest, heart attack, rupture of aortic aneurysm or myocarditis, as well as respiratory problems and severe allergic reactions, and finally - death.
The National Institute of Public He alth - National Institute of Hygiene has published another report on the number and type of adverse vaccination reactions to COVID-19 vaccines reported in Poland in the period from December 27, 2020 to December 15, 2021. The reported NOPs concern all four vaccines against COVID-19 used in Poland - COMIRNATY (Pfizer-BioNTech), VAXZEVRIA (AstraZeneca), SPIKEVAX (Moderna), COVID-19 VACCINE JANSSEN (Johnson & Johnson).
NIPH-PZH informed in the report that by December 15, 2022, a total of 44,433,935 vaccinations were performed and a total of 16,677 NOPs were registered. Therefore, these data show that adverse vaccine reactions have occurred so far in the case of approx. 0.05 percent. injection.
Percentage of NOPs after vaccines
These numbers are as follows:
- 85 percent reported post-vaccination reactions (11,443 cases) are mild NOPs.
- 11.5 percent (1,553 cases) are NOPsserious.
- 3.5 percent (470 cases) are heavy NOPs.
