Generally, there are only two types of vaccines for cats, , one is Miaosanduo , and the other is Mao Sanlian , and both of them are imported.
Then why are there only these two types? The answer is very simple, because only these two are the most reliable.

After all, is a cat vaccine reliable? The market can verify the incidence of cats in less than a year. You don’t need to carry out various publicity and flattery.
These two vaccines are imported from abroad, so is there any domestic vaccine that can be used? Of course there is, but this is just a reliability, which means that you can’t have an immune effect after the injection, or whether the effect is significant.
is almost the same as the manufacturing of chip . Although there are indeed many related companies, the strongest ones are TSMC and Samsung .
In the field of semiconductor , we are stuck in the Western countries. There is no way, the chips that mobile phones and computers need to be used, and everyone is still paying great attention, but what about the field of biotechnology?
In fact, judging from the situation of this cat vaccine, it can probably be seen.
Cat vaccine is monopolized by two foreign companies. What does this mean? We are also stuck in the high-end biotech field.
Generally, the production of a vaccine takes five to ten years, or even longer, from development to approval for marketing. If it is fast, it will take two or three years, but there are exceptions. For example, the new crown vaccine , the fastest one is said to only take a few months. The speed of exceptions like
is mainly reflected in the urgency of producing this vaccine. But on the other hand, even if time is tight, it still takes a relatively long time for a new vaccine to go from development to production.
Under normal circumstances, as long as you are willing to spend time and the time is long enough, there will definitely be a result. This logic should be correct.
But we still need to know that from research and development to production a new vaccine, the premise is that it requires decades of technological precipitation before it can achieve the aforementioned way of compressing the development of vaccines with production cycle to several months. The essence of the
vaccine is some of the weakened or has no activity, but it still maintains its basic protein structure, or it may produce part of the protein owned by the virus itself. The effective vaccine for the new coronavirus is basically this method, using the virus's spike protein as the main component of the vaccine.
Then when these vaccines are injected into the human body, the human immune system knows in advance that there are these foreign viruses and makes corresponding defense plans at the same time to prepare for the real virus to invade. The immune system can respond as soon as possible and finally clear the corresponding invading viruses.
But how to weaken the virus, or kill them without destroying their protein structure, or create some proteins with viral characteristics? This is actually a high-end biotechnology.
As mentioned earlier, in the high-end field of biotechnology, we are still stuck like chips.
Whether it is a vaccine used for humans or a vaccine used for cats, although the manufacturing methods themselves are different, the principles followed are basically similar, except that the types of viruses are different. Although there are many methods for
, because there is not enough technical precipitation in this field in China, it is theoretically not difficult to produce a vaccine, but it is unrealistic to produce a vaccine with significant effect within two or three years because of a new virus.
So what is a vaccine with significant effect?
We understand from the effective ingredients of vaccines that they are basically either dead viruses or some highly recognizable proteins of viruses.
Some people with common sense in biology basically know that biological protein is very complex, but because of the complexity, their stability is not high, and it is easy to cause some deformation due to some temperature, pH, or other physical and chemical conditions. Once the
protein deforms, some of its original characteristics will disappear.
So you probably understand why some vaccines work, but some are ineffective? The key technology is to keep some characteristics of the virus as much as possible while ensuring that the vaccine is safe, and the characteristics of these viruses are the effective ingredients of the vaccine.
So this is very easy to arise in the process of vaccine research and development and production. Theoretically, some companies with less technology need to ensure safety when they get a vaccine, the more likely they will destroy some characteristics of the virus. So the final result is that the vaccine is 100% safe, but the virus characteristics in the vaccine also disappear 100%.
. Although the virus characteristics in the vaccine have not disappeared 100%, the overall content is insufficient, that is, the dose is insufficient, so the effectiveness of the vaccine is naturally not high.
Some time ago, some people suggested online that foreign vaccines are needed to be introduced in China so that some old and young groups can be better protected. However, some big Vs use their usual class struggle ideology to satirize, and always say something like what interests, what forces, or even traitors.

Actually, it’s quite ridiculous to think about it, and what’s even more ridiculous is that there are some people below who follow the trend and scold those who say they want to introduce foreign vaccines.
It’s fine if you can’t see other people’s situation clearly, but you don’t even want to see your actual situation and your strength at any level.
So what is this called? Hard but not strong.
