Russian to English Medical Medical (general) Immunology

Found on an inoculation list, occurring both with and without an abbreviation dot after it, according to the individual handwriting.

Full line for context:

[date] 14/IX-02 2 Т.С. с 06-88 к. 309 г.

Another example (again, the full line is given):

[date, ending with Cyrillic letter г] с 244

And another:

V2 [date] 0,5 с. 7 с 165

One more:

RV паротита — [date, again ending with г] 0,5 с 0186

Would also be grateful for confirmation that г is part of the date, and what it might mean in this line:

[date] 2 Т.С. с 06-88 к. 309 г.
