Vaccination has been carried out more than 1.3 million times in Latvia, including both the first and second doses of the vaccine. Adverse reactions to Covid-19 vaccines have been reported 1,877 times.
There have also been 24 reports of fatal cases, of which 16 reports received have been evaluated. In eight cases, the evaluation is still ongoing due to the request for necropsy and other information. No fatal cases have been confirmed in Latvia, which, on the basis of data available to the ZVA, would currently have a credible causal relationship with vaccination.
Based on currently available information from ZVA, no cases of thrombosis or thrombocytopenia syndrome have been identified in Latvia and no cases of increased capillary permeability syndrome following vaccination with Covid-19 vaccines have been found.
In relation to other cases of serious side effects, the ZVA indicates, four reports of anaphylaxis, a severe allergic reaction, have been filed in Latvia. Patients were given immediate medical treatment and all have now recovered.
Five reports on myocarditis have been received in Latvia by July 22. In four cases, a reliable association with vaccination has been confirmed, but in one case there is no conclusive evidence of myocarditis. Information at the disposal of ZVA shows that patients have recovered and studies do not show persistent changes in the heart muscle.
One possible adverse reaction report on Guillain-Barré syndrome has also been received in Latvia following vaccination with a virus vector vaccine.
In Latvia one person is known to have turned to the Medical Risk Fund, requesting compensation for vaccination against Covid-19. The Health Inspectorate indicated that the case has not yet been examined because the applicant had not yet provided full information.
ZVA recalled that all medicines, including vaccines, can have side effects, but not everybody gets them. The most common side effects of Covid-19 vaccines are increased body temperature (sometimes above 38 °C), fever, headache, dizziness, fatigue, somnolence, muscle and joint pain, and nausea, diarrhoea, vomiting. All these flu-like symptoms typically start 8 to 10 hours after receiving the vaccine and disappear within 2 to 3 days.
