The new crown vaccine, jointly developed by Pfizer Pharmaceutical Co., Ltd. of the United States and new biotechnology company of Germany, has been put into use in Europe since December last year. However, Pfizer recently said that it would temporarily reduce the delivery of its new crown vaccine, which affected the vaccination plans of many countries in Europe and America and caused dissatisfaction from many countries. At the same time, low-income countries and most middle-income countries have not yet started vaccination, and the equitable distribution of new vaccines in the world is facing challenges. Pfizer recently said that in order to achieve the goal of increasing vaccine production, the company will change the production process and “temporarily affect” the vaccine delivery schedule from the end of January to the beginning of February. Production at a plant in the Belgian town of Peirce will fall in the next few weeks as the company changes some production processes to increase capacity, German biotech said. A Pfizer spokesman said the delay would affect all European countries. < / P > < p > the health ministers of EU Member States held a video conference on the 13th of this month to discuss vaccine delivery. Sweden, Denmark, Finland, Lithuanian, Latvian and Estonian wrote to the European Commission on the 15th, asking the European Commission to put pressure on Pfizer and biotechnology companies to ensure timely, stable and transparent vaccine delivery. “This situation not only affects the established vaccination schedule, but also undermines the credibility of vaccination plans,” the health ministers of the six countries said in their letter < / P > < p > Pfizer’s practice has also been strongly criticized by Swedish health and social affairs minister Lena harrengren and other European health ministers. “It’s unacceptable,” Swedish news agency quoted harrengren as saying. “We are racing against the new coronavirus and the more infectious mutant virus We therefore attach great importance to the reduction of vaccine delivery. ” < / P > < p > other European and American countries are also affected by Pfizer’s reduced delivery. French Minister in charge of industry Agnes panier renacher told French TV News Channel 4 on the 18th that France expected to receive 140000 fewer Pfizer vaccines this week. Domenico alcuri, Commissioner of Italy’s new coronavirus emergency committee, said Pfizer will cut the dose of vaccine delivered to Italy by 29% from the 18th. Pfizer did not say how long the supply reduction will last. In addition, Poland, Finland, Canada and Mexico also said that they received less Pfizer vaccine than the original amount, which will affect their vaccination services. < / P > < p > during his visit to Portugal on the 15th, European Commission President von Draine told the media that the European Union is very concerned about Pfizer’s announcement of delaying the supply of vaccines, especially that many people have already received the first dose, and they need to receive the second dose four weeks later. Van der lain said that the supply delay just shows the importance of expanding production, and the EU will continue to promote cooperation with pharmaceutical companies in this regard. But Mr. von der lain did not say how many doses Pfizer would be able to provide when normal supply resumed in February. < / P > < p > Pfizer is not the only pharmaceutical company to delay vaccine delivery. Nazim Zahavi, an official in charge of the new crown vaccination program of the British government, said in an interview with the media on the 18th that the British government had hoped to receive 2 million doses of vaccines produced by AstraZeneca a week by the end of January at the latest, but the pharmaceutical company could not reach the delivery volume until mid February. < / P > < p > in the face of insufficient vaccine supply, some countries consider adjusting vaccination strategies. According to U.S. media reports, some U.S. officials suggested that the dose of Modena vaccine should be halved to some people, so as to “double the number of vaccinated people under the existing vaccine stock”; in December last year, the UK changed the recommended interval of Pfizer vaccine from 21 days to “at least 21 days” and the longest “no more than 12 weeks” to increase the number of vaccinated people within a short period of time Count. However, similar views have been questioned. Pfizer has said: “there is no data on vaccine protection more than 21 days after the first dose.” < / P > < p > compared with developed countries, it is more difficult for low-income countries and most middle-income countries to obtain vaccines. According to the data released by the World Health Organization on the 8th, 42 countries are currently promoting new crown vaccination, of which 36 are high-income countries and the remaining 6 are middle-income countries. Low income countries and most middle-income countries have not yet started vaccination. The world is on the verge of a “catastrophic moral failure” because poor countries do not have access to vaccines as quickly as rich countries do.
