This brings the total number of doses to be delivered to the EU to million. Events of anaphylaxis have been reported. Appropriate medical treatment and supervision should always be readily available in case of an anaphylactic reaction following the administration of the vaccine. The efficacy, safety and immunogenicity of the vaccine has not been assessed in immunocompromised individuals, including those receiving immunosuppressant therapy. Individuals may not be fully protected until 7 days after their second dose of vaccine. A slightly lower frequency of reactogenicity events was associated with greater age. The black equilateral triangle denotes that additional monitoring is required to capture any adverse reactions. This will allow quick identification of new safety information. Individuals can help by reporting any side effects they may get. At Pfizer, we apply science and our global resources to bring therapies to people that extend and significantly improve their lives.

Eukaryotic organisms that cannot be classified under the kingdoms Plantae, Animalia or Fungi are sometimes grouped in the kingdom Protista. The eukaryotes are usually now regarded as having emerged in the Archaea or as a sister of the now cultivated Asgard archaea.
Eukaryotic cells typically contain other membrane-bound organelles such as mitochondria and Golgi apparatus ; and chloroplasts can be found in plants and algae. Prokaryotic cells may contain primitive organelles. Animalsplantsand fungi are the most familiar eukaryotes; other eukaryotes are sometimes called protists.

Eukaryotes can reproduce both asexually through mitosis and sexually through meiosis and gamete fusion. In mitosis, one cell divides to produce two genetically identical cells.
In meiosis, DNA replication is followed by two rounds of cell division to produce four haploid daughter cells. These act as sex cells or gametes.
Each gamete has just one set of chromosomes, each a unique mix of the corresponding pair of parental chromosomes resulting from genetic recombination during meiosis. The concept of the eukaryote has been attributed to the French biologist Edouard Chatton — The terms prokaryote and eukaryote were more definitively reintroduced by the Canadian microbiologist Roger Stanier and the Dutch-American microbiologist Article source. In his work Titres et Travaux Scientifiques[17] Chatton had proposed the two terms, calling the bacteria prokaryotes and organisms with nuclei in their cells eukaryotes.
However he mentioned this in only one paragraph, and the idea was effectively ignored until Chatton's statement was rediscovered by Stanier and van Niel. In andthe Russian biologist Konstantin Mereschkowski — argued that plastids were reduced cyanobacteria in a symbiosis with a non- photosynthetic heterotrophic host that was itself formed by symbiosis between an amoeba-like host and a bacterium-like cell that formed the nucleus.]
What nice message
In it something is. Now all became clear to me, Many thanks for the information.
I regret, that I can help nothing. I hope, you will find the correct decision. Do not despair.
