For over a year now, the world has been fighting the Covid-19 pandemic. Since the beginning of the pandemic, the coronavirus has been detected in more than 127 million inhabitants of the planet, almost 2.8 million people have died, 103 million have recovered. The coronavirus vaccination began in December 2020. True, the effectiveness of the vaccines still does not show 100%.
The development of the vaccine began in January 2020, and already in March about 300 studies were carried out. Today only a few vaccines are used in the world, among them Pfizer / BioNTech, Moderna, AstraZeneca, Sinovac Biotech, CNBG, Johnson & Johnson and Sputnik V. As of the end of March 2021, 82 candidate vaccines are in clinical trials and 182 are in preclinical studies. Scientists are confident that the world needs a wide range of vaccines, in the future this will help effectively treat people with different health conditions.
Intrigues, scandals, vaccines
The global accination lasts only about 4 months, nevertheless, several high-profile scandals have already shaken the world. In early March 2021, several European countries suspended the use of the AstraZeneca vaccine. The fact is that a number of patients allegedly developed blood clots after vaccination, which led to death. However, it was not initially established that this is a side effect of the AstraZeneca vaccine. Nevertheless, such statements led to the fact that the level of confidence in the vaccine in European countries fell sharply and its use was temporarily stopped. Later, the European Medicines Agency approved further vaccination against coronavirus with AstraZeneca, as the regulator did not identify the possibility of increasing the risk of thrombosis from the vaccine. The vaccine was rehabilitated, but the sediment remained.
Perhaps it was these events that led to the announcement of the renaming of the drug AstraZeneca on March 30. It is now called Vaxzevria. The composition of the vaccine has not changed, only the name, packaging and labeling have changed.
The government brought the Indian analogue of AstraZeneca, the drug CoviShield, to Ukraine for vaccination. And here, too, there was a scandal. Since we were promised the AstraZeneca vaccine, and not its Indian version, this provoked a lot of indignation and far from flattering reviews both about the vaccine itself and about the government. It took a long time to prove that the vaccine is safe, effective, and to persuade the population to somehow start vaccination. For example, President Zelensky and Leonid Kravchuk, chief medical officer Viktor Lyashko were vaccinated on camera. Health Minister Maxym Stepanov said that he vaccinated his parents, bloggers, influencers and other media personalities joined the company.
But as soon as the passions began to calm down a little, there were official statements from other countries about not recognizing the CoviShield vaccine. And India announced that it is stopping the supply of its vaccine to Ukraine. At the same time, some Ukrainian MPs concluded that the discrediting statements against CoviShield are to blame. Like, India freaked out that its vaccine was offended. True, the Ukrainian Foreign Ministry officially stated that all this is lyrics. They say, yes, deliveries from India have been suspended, but they are also suspended because India is faced with a new surge in the incidence and intends to expand the campaign to vaccinate the population.
There are very few vaccines in the world, more is needed
The most sought after, effective and recognized worldwide remain Pfizer, Moderna and the original AstraZeneca, now Vaxzevria. But this does not stop scientists around the world to continue to work on the creation of new vaccines against coronavirus.
First, the existing ones, even taking into account the Indian, Chinese and Russian ones, are still not enough for everyone. The World Health Organization has called on wealthy nations that already have enough doses of coronavirus vaccine to share with the poorest nations that have not yet launched a campaign to immunize their citizens. The demand is great, the supply cannot cover it.
Second, as we have said, the more varieties of vaccines, the more likely it is that one will be effective for one group of people, the other for another.
Brazil said it has invented a new and cheaper coronavirus vaccine, ButanVac. And already in May of this year it plans to launch its serial production.
In theory, Ukraine can also create its own vaccine. Maxym Stepanov said that Ukraine can start production of its own drug if domestic producers receive support from the state. In his opinion, the government should issue a state order, giving clear guarantees to manufacturers that their products will be bought.
The third coronavirus vaccine was registered in Russia. To the already existing Sputnik V and EpiVacCorona was added CoviVac.
But the best vaccine against Covid-19 is planned to be created in Belarus. Alexander Lukashenko called on Belarusian scientists to create a vaccine against Covid-19 as soon as possible, saying that obtaining their own vaccine is a matter of honor for the leadership of the Ministry of Health.
And scientists are clearly not going to stop there. This in general is very good for you and me and our future. Healthy competition will only spur the best minds of mankind to active work. So we will defeat the coronavirus.
