Recently carried out in-vitro tests show that the active ingredient carragelose, which is obtained from red algae and contained in the nasal spray algovir, can inactivate the alpha, beta and gamma variants of the SARS-CoV-2 virus [1]. Even with the increasing prevalence of these virus mutants, algovir remains an effective option for minimizing the risk of Covid-19 infection in addition to general hygiene measures – also for pregnant women, breastfeeding women and children from one year old.

The Carragelose contained in the cold spray algovir is a natural active ingredient from red algae with a broad spectrum of action against a large number of viruses that cause respiratory diseases such as flu. Carragelose forms a protective film on the nasal lining and prevents the viruses from attaching to the cells in the lining. This reduces their multiplication and spread in the body. A number of previous laboratory studies with cell cultures [2,3,4,5] and a clinical study [6,7] were able to show that Carragelose also inactivates the SARS-CoV-2 virus in the wild-type variant.

New in vitro tests now confirm that this also applies to the alpha (B.1.1.7), beta (B.1.351) and gamma (P.1 *) mutants with similar effectiveness [1]. This is relevant insofar as the virus variants now clearly determine what happens in the pandemic. According to the Robert Koch Institute, the alpha variant first discovered in Great Britain has long dominated in Germany. Their share in samples tested for SARS-CoV-2 was already almost 92 percent at the beginning of May [8]. The carragelose-containing nasal spray algovir (from the pharmacy) remains an option that goes beyond general hygiene measures in order to minimize the risk of Covid-19 infection.
