ZVA informed that by 31 December 2021, 3045 have been received in Latvia side effects have been reported with Covid-19 vaccines. To date, vaccination has been performed more than 2.5 million times in Latvia.
The vast majority of people have reported reactions to the vaccine as described in the package leaflet, such as pain at the injection site, fever, chills and tiredness. These symptoms usually occur within 8 to 10 hours after vaccination and resolve on their own within 2 to 3 days.
Of all reports of suspected adverse reactions to Covid-19 vaccines received in Latvia up to 31 December, 667 or 22% were classified as significant. This means that reactions have been reported in these cases, such as what the doctor thought was a medically significant reaction or when the patient was hospitalized. This does not mean that not all of these reported cases have been associated with the use of the medicine, ie that a side effect has been confirmed. To determine this, these reports are carefully evaluated and, if necessary, additional information is collected.
So far, no fatal cases have been confirmed in Latvia that would be reliably related to the receipt of the vaccine against Covid-19, the ZVA indicated.
As of 31 December, the MAH had received 43 adverse reaction reports providing information on fatalities occurring several days and several months after vaccination. Of the 43 reports, 22 cases have been closed. In 21 cases, the evaluation continues because autopsy results and other information are requested.
Based on the evaluation of the data submitted so far by the ZVA for the mentioned cases, it is not possible to reliably link the occurrence of a fatal case to vaccination in any of them. For some of the reported cases, it is expected that the SAA will still receive the requested additional information in order to complete the assessment of the reported cases.
In several cases, fatalities have occurred due to serious, chronic diseases. The most frequently reported fatalities have not been associated with possible adverse reactions to Covid-19 vaccines that could be fatal, the MAH explained.
The benefits of Covid-19 vaccines still outweigh their risks. The data show that the side effects of Covid-19 vaccines are generally incomparably less severe and less common than those of Covid-19, and the disease itself protects against, according to the ZVA.
The MAH recalled that, as with any vaccine or medicine, side effects may occur after receiving Covid-19 vaccines. Most side effects occur because vaccines stimulate the human body’s immune system. As a result, some people may experience reactions or side effects due to the nature of their body. However, the occurrence or absence of such reactions does not indicate the degree of protection afforded by the vaccine.
