As of the publication of this strip, it is estimated to have caused over 1.5 million deaths worldwide, with over 300,000 deaths in the United States, with many more cases that have not resulted in fatality but far too often needing serious medical support and/or with lasting implications. Even for those who have been spared infection, measures to slow the spread of the virus have been highly impactful, and have been ongoing for nearly a year. |

Many people online have been sharing plans for what they'll do after getting the vaccine, like "see my friends" or "travel the world." In this comic, Ponytail takes the trend literally, listing instead what will happen in her body immediately after getting the vaccine: |
− | + | - First she will make some spike proteins. This implies that she took an mRNA vaccine (e.g. from BioNTech or Moderna). These vaccines contain RNA encoding for the viral proteins, which is then used by Ponytail's cell to make the spike protein. (In contrast normal vaccines already contain the viral proteins e.g. the one from AstraZeneca). | |
− | + | ||
− | + | - The spike protein made by Ponytail will then be recognised by her immune system as foreign (as would the proteins of a normal vaccine or the real Coronavirus) and subsequently engulfed by the dendritic cells in a process called phagocytosis. | |
− | + | ||
+ | - The dendritic cells then chop the spike proteins into small pieces (called antigens) and present them on their surface using MHCII proteins. | ||
+ | |||
+ | - This will then allow T-cells to recognise these pieces and become activated if they have a matching T-cell receptor. | ||
The next step is mentioned in the title text: | The next step is mentioned in the title text: | ||
− | + | - The T-cells will activate B-cells, who will then try to make antibodies to bind the spike protein. Since the B-cells don't know how a good antibody looks like, they just randomly generate antibodies through a process somatic hypermutation. Then they check if the antibody binds the antigen presented by the dendritic cells. If it doesn't the antibody is discarded, if it does, it is kept and improved on by another round of somatic hypermutation, to create an antibody which binds even better. | |
− | + | ||
+ | - Finally Ponytail mentions the one thing she herself (as opposed to her immunes system) has to do: continue to use social distancing, hand washing, wearing a mask etc. | ||
+ | |||
+ | This is important because while the vaccine will eventually protect her ''after'' the protein has been made, engulfed by the dendritic cells etc. this process takes time, during which Ponytail is still vulnerable to the virus. This can for example be seen in the graph presented in [[2400: Statistics]]: While eventually there is a clear difference between the vaccinated and the placebo group, they contract Covid at the same rate in the beginning, when the immunesystem is still busy presenting the antigens to T-cells and creating antibodies through somatic hypermutations. | ||
− | + | If Ponytail were to go out and socialise before her immunesystem has finished its work, she would be at risk of contracting the Coronavirus, making the vaccination pointless. | |
− | + | The title text emphasizes the real danger for and from people planning what they'll "do first": they won't have immunity immediately after receiving the vaccine. Developing immunity takes weeks to be effective. The first few vaccines likely to be approved will require a second dose 3 or 4 weeks after the first. Moreover, a person with immunity might still be able to spread the virus even if they don't get sick themselves. | |
