Derek Lowe over at Science has a roundup of the status of current (article published 29 June 2020) Coronavirus vaccine trials/research.
This roundup of current vaccine research/trials includes information about many vaccine trials, broken down by vaccine types. These types include (quotes are all from TFA:
- Viral Vectors
This class uses some other infectious virus, but with its original genetic material removed. In its place goes genetic instructions to make coronavirus proteins, and when your infected cells do that, it will set off an immune response.
Number of trials (per TFA): 9
- Genetic Vaccines
These take DNA or RNA coding for coronavirus proteins and inject that directly into the bloodstream. "Directly" isn't quite the right word, though – for these things to work, they have to be formulated and modified to survive destruction in the blood, to be taken up through cell membranes, and to be used for protein production once they're inside.
Number of trials (per TFA): 8
- Recombinant protein vaccines
Here we get to a technique that really is used for human vaccines. The previous two categories force your own cells to make viral antigen proteins, but here you're making them industrially and just injecting them directly. The advantage can be that such protein production can be accomplished in many different ways and is already done on a large scale. That said, every new protein is a new project, with its own idiosyncrasies.
Number of trials (per TFA): 6
- Attenuated Virus Vaccines
This is another well-precedented vaccination technique. It involves producing a weakened form of the actual infectious virus, one that is not capable of causing damage but can still set off the immune system. There are several ways to do this, and it's a bit of an art form involving taking the virus through a huge number of replications in living cells as you select for variants that are less and less harmful.
Number of trials (per TFA): (None listed)
- Inactivated Virus Vaccines
This is also one that's also been used in medical practice for many years, and it's another inactivation step beyond the attenuated viruses. Heat or chemical agents are used to damage the virus to the point that it can no longer infect cells at all, but the plan is for there to be enough of the viral material left unaltered to still raise an immune response.
Number of trials (per TFA): 4

There have been multiple studies on this: There is no evidence at all that protests have been what's been spreading Covid-19. The protesters you're talking about for the most part have been socially distancing and wearing masks and are outdoors. You're basically relying entirely on post hoc ergo propter hoc, which isn't actually proof of anything.
What's definitely a factor is large gatherings indoors. For example, attending one of those with sick people present is why Herman Cain is now in the hospital.

No, the protesters here in SoCal were not wearing masks and were not socially distancing while they looted and burn't down historic buildings. And the spike in cases is also right here.

But that's okay - the cops die at an average age of 60 from pre-existing conditions - 80% die from obesity and heart disease. Help save a pigs fife - defund the police so they have to get an honest job that requires them to get off their obese butts.

You weren't there, I saw the bullshit go down 3 nights in a row from my yard. Both antifa and white trash came in from other areas, were in large groups across the street from each other, no masks, and lots of clashes between them. You don't see this shit on the news coverage.

That is the most amazing virus ever. It knows if you are protesting and will not spread!

Rioters, as distinct from protestors, try to ensure that they're not recognized. Claims to trace them and their contacts must be considered unfounded.
In any case, these things aren't spontaneous.They're planned in untelevised, unrecorded meetings, most likely in small hidden places. Perfect for transmission. Keep in mind that these are people who want to make trouble, so the desire to spread the disease is limited only by the desire to not be personally infected.

You mean, on Twitter and by text?
These are people who live in fear for their lives. In my country, we have first nations without safe drinking water supplies. They "make trouble" too. George Floyd "made trouble" when he cried for help, and for his mother, as he died.
You're either evil or clueless. I hope the latter, in which case, please go do some reading. Maybe investigate disparities in other nations - Indigenous communities in Colombia and First Nations in Canada, off the cuff - so that your personal local biases get less in the way of seeing the truth.

There is a point where Hanlon's Razor ("do not attribute to malice what may be explained by stupidity") loses its edge. At some point, willful ignorance becomes malicious. The AC you're replying to has long since passed this point.

There have been weeks of protests, CHAZzes and CHOPs since June. It's too soon for peer unreviewed "studies" to exonerate them.
