Why can't we just let other countries replicate the vaccines?

Orthodoxy is the only true faith. Rapture = heresy; Fireball should be beheaded for spreading this heresy on Yahoo Answers (deceiving Christians into false hope). Dreams/thoughts are from 1)angels who always do good; 2)demons who never do good; or 3)you making shyt up in your head while you sleep trying to solve your problems; or from 4) your gov't using this supertechnology. Usually, dreams/thoughts are from demons. So, that explains a lot of people being in the wrong all the time. Rapture thing is from demons but you can't rule out the gov't using some super technology like Project Blue Beam to kind of introduce people to the evil flying antichrist who will ride on a donkey into the Third Temple. So, churches who closed for COVID (or had COVID measures like dipping spoon into some liquid like alcohol) are no longer Christ's but now are working for Satan promoting the new COVID religion. Last Patriarch is Patriarch Irenaios 1st. He blessed Catacomb movement. For liturgy what you need is antiminis (towel with remains of saints sewn into it); wax candles; one cup/one spoon; non-Kosher non-yeast non-barcoded non-qrcoded wine/bread. Kosher = sprinkled with blood. Yeast is grown on pig bacteria. QRcode = barcode = mark of the beast. Roman Catholics tried one cup and one spoon and got sick with Bubonic plague (no laughing matter). You must hide (within a small group of 10-15 people according to saints Gabriel Urgebadze and Seraphim of Sarov) in order to escape the unforgivable mark of the beast. No documents once you hid because documents are from Satan; burn all the documents that you can find. No electronics once you hid because antichrist's minions will track you using electronics that you got. Even old broken unplugged 1970 TV set will show the antichrist using Tesla's ether. In case you're in 'Murica and want to hide, then consider inland Alaska. Arctic Circle = Security Circle for WW3. If you manage to escape the unforgivable mark of the beast, then your direct ancestors will go to heaven (according to saint Vyacheslav Krasheninnikov). Thanks for reading this spiel. Forgive me.

Some countries do through partnerships

An example is NovaVax which has already signed an agreement with a pharmaceutical country in India to manufacture NovaVaxes vaccine

Only certain drug companies have specialized super expensive equipment in a huge manufacturing plant and the hundreds of highly trained technicians to make any drug or any vaccine.  Those facilities capable of making enough vaccine to be shared are located in  only few countries.Giving out studies and formula would be useless.

Money money money

Who is "we"?

Producing vaccines may take very specialised equipment, and farmaceutical companies are not going to give other companies the recipe without proper financial compensation

When a pharmaceutical company researches new drugs it takes a long time, costs huge sums of money and only a small percentage of putative medicines that start the process are found to work and make their way into use.

A pharmaceutical company makes no income from its medicines until they have been approved and licensed for use. To enable them to recoup their costs and to have the funds for research and development they are usually allowed to patent their drug for a certain length of time. When that time expires they have to make the information on how to manufacture the drug available.

There are lots of small pharmaceutical companies that do no research and development but simply manufacture drugs under their generic name that are out of patent.

I cannot see the pharmaceutical companies that developed the COVID-19 vaccines simply giving away the drug details so small pharmaceutical companies can produce them cheaply. The companies that developed them are commercial enterprises not charitable organisations.

Vaccines could be made more widely available if richer countries and inter-governmental organisations provided funding to purchase vaccines for poorer countries.

It is not only the rich West that should be held to account. There is no reason why the governments of many poor countries could not purchase the vaccines from the manufacturers. They receive billions per year in aid from the rich West. The problem is much of this aid never reaches the people but ends up in the pockets of their despotic rulers.

Countries don't manufacture vaccines. Pharma companies do that. They have to recover their outlay and overheads to stay in business. So they won't allow replication without issuing a licence. That's always been true of all vaccine production. No doubt there will be arrangements in place but there has to be a company capable of copying the vaccine under licence.

only advanced places have the ability to mfg

Because money is apparently more important.
