There is no hard and fast answer to your question

Which is because the risks associated with taking the pup out for socialisation varies according to where you live, and where you're going to take her.
IMO socialisation is extremely important - and the experiences she needs as a baby puppy cannot be replicated once she's older. What she learns now, and is exposed to now, are the things that are going to shape her later. If she's too sheltered, that cannot be undone.
At the same time, you've got to be aware of the risks of taking her out - and not take undue risks.
Places to avoid include any sort of dog park, places where unknown animals (unknown temperamentally, uncontrolled, or those you don't know the medical history of) congregate and especially defacate, or contact with said unknown dogs.
But that doesn't mean that she can't go out - it just means that you should be conscious of where you take her. From a disease perspective, the most risky places are the above places where dogs congregate - and vets' offices (where sick animals congregate).
So it makes much more sense to restrict her socialisation to places without other dogs, play dates with one or two dogs that you
know are not sick and are up to date on their shots (and who themselves don't frequent dog parks), and puppy kindergarten classes - where the other pups should be similarly protected by their new owners.
