Because the vaccine is a chemical preparation, it must not react with the device for storing the vaccine, so the bottle for storing the vaccine is not an ordinary glass bottle, but a medium boron silicon glass bottle, which has stable chemical properties and hardly reacts with other substances. Glass bottles made of this material are also the standard requirements for storing chemicals in most countries.
In addition to these factors, the demand for the most critical vaccine bottles is too large, resulting in insufficient manufacturers and inability to produce sufficient quantities. According to the current epidemic situation in novel coronavirus, the global demand for vaccine bottles exceeds10 billion.
At present, the global population exceeds 7 billion. In order to completely control the spread of the novel coronavirus epidemic, the vaccine coverage rate should reach at least 90%, and it is best to cover all of them. That is to say, almost everyone should be injected, and the success rate of the vaccine is over 90%. However, it is best to take two shots for safety.
As a result, the global demand for vaccine bottles has reached more than 654.38+0.4 billion, which is an ideal situation that all vaccines can be injected in a short time, but it is impossible in practice. That is to say, in order to avoid being infected after the expiry date of the vaccine, people who started to take COVID-19 vaccine need to be vaccinated again, because they will not produce permanent immune antibodies against novel coronavirus.
This means that the global demand for COVID-19 vaccines will be even greater, and the demand for vaccine bottles for storing vaccines will be even greater. However, it is impossible to suddenly explode huge production in a short time, resulting in a global shortage of vaccine bottles for storing COVID-19 vaccines. If the effective storage period of COVID-19 vaccine is taken into account, the world demand for COVID-19 vaccine bottles will be even greater.
